Sen. Barack Obama's choice for running mate will be announced to supporters in a text message Saturday morning, senior Obama campaign officials told CNN on Friday night, and a senior party official said it won't be Sen. Hillary Clinton. Obama called some people on his short list for the vice presidential slot Thursday night to tell them he had not selected them as a running mate, a highly placed Democratic Party source said.

A senior Democratic official who had spoken with Clinton told CNN late Friday that the Obama campaign has communicated to her through private channels that she will not be Obama's vice presidential pick. Also, sources close to Virginia Gov. Tim Kaine said he has been informed he was not selected. One source told CNN that Obama personally made the call to Kaine. Another source said Kaine has flown to Denver, Colorado, for the Democratic National Convention. See who's in the running

It is not known who else may have gotten calls. However, late Friday two Democratic sources confirmed that Indiana Sen. Evan Bayh is also out of the running. Most of this week's buzz had been around Bayh of Indiana, Sen. Joe Biden of Delaware and Kaine. The contenders kept a low profile and Biden has avoided any lengthy interviews. Rep. Chet Edwards said Friday that the campaign had vetted him but that he hasn't talked to Obama. VideoWatch panelists weigh in on top VP contenders » Edwards, 56, is a nine-term congressman representing the Central Texas district that includes President Bush's ranch near Crawford.

Facing imminent impeachment charges, President Pervez Musharraf announced his resignation on Monday, after months of belated recognition by American officials that he had become a waning asset in the campaign against terrorism.

The decision removes from Pakistan's political stage the leader who for nearly nine years served as one of the United States' most important — and ultimately unreliable — allies. And it now leaves American officials to deal with a new, elected coalition that has so far proven itself to be unwilling or incapable of confronting an expanding Taliban insurgency determined to topple the government.

"Whether I win or lose the impeachment, the nation will lose," Mr. Musharraf said, explaining his decision in an emotional televised speech lasting more than an hour. He will stay in Pakistan and will not be put on trial, government officials said. The question of who will succeed Mr. Musharraf is certain to unleash intense wrangling between the rival political parties that form the governing coalition and to add a new layer of turbulence to an already unstable nuclear-armed nation of 165 million people.

"We've said for years that Musharraf is our best bet, and my fear is that we are about to discover how true that was," one senior Bush administration official said, acknowledging that the United States had stuck with Mr. Musharraf for too long and developed few other relationships in Pakistan to fall back on.

Tom Foreman: Even if we consider that though, what do we make of moves like this talk about the missile shield in Poland? Certainly the Russians say that is a direct slap at them over this problem in Georgia. Is it, to your read and is it a smart move?

GENERAL WESLEY CLARK: Well no, it's not a direct slap at them, and it's something that's been on the books for a long, long time. We've talked about this for a decade, and they've been consulted on it. They've met with it. They know what the capabilities of the system are. This is just an example of Russian rhetoric aimed at intimidating Europe. It doesn't intimidate the United States. But the United States' reaction then can either bring Europe together with the United States or we can chill the relations with Europe. So, we want to be careful. This, this is not something that the Russians have a right to respond on, and their response is unjustified. But on the other hand, we want to make sure our European allies all see it our way.

Tom Foreman: How do you read Putin's intentions right now when you look at Georgia and you look at his response to the rest of the Western world over issues like Iraq and Iran and oil supplies and everything?

GENERAL WESLEY CLARK: Putin believes in re-establishing Russia's power. He wants Russia to be an important factor in every issue in the world. He'd like to regain the empire that Russia lost with the breakup of the Soviet Union. He'd love to see the reintegration of Ukraine. Belarus wants to be reintegrated. The Russians've put that on hold, because it's such a basket case. But with Ukraine and Belarus together, then the absorption of some of these other countries, he believes, that are on the periphery could happen, and Russia would once again be a, a much great- it'd be a superpower - unlike what it is today except through the nuclear capacity of course. And so, Georgia, in Putin's mind is probably the first step. They've long prepared Ossetia, South Ossetia and, and Abkhazia along with other areas on the periphery of Russia as, as, a-as grips into the near, what they call 'the near abroad'. This is a strategic crisis. It's been building for a long time. It just broke out into the open now, but we've seen its roots back more than a decade.

The president, speaking at the White House with Ms. Rice and Defense Secretary Robert M. Gates, criticized Russia and called on it to "keep its word and act to end this crisis." Mr. Bush said that a transport plane with medical supplies was already on its way to Georgia, and that American air and naval forces would carry out the aid mission. And he said pointedly that Russia must not interfere with aid arriving in Georgia by air, land or water.

But while Mr. Bush said the United States "stands with the democratically elected government of Georgia and insists that its sovereignty and territorial integrity be respected," his remarks contained no hint of an American military role in Georgia, other than providing humanitarian assistance. However, minutes after Mr. Bush's comments, President Mikheil Saakashvili of Georgia characterized the import of the American aid as "definitely an American military presence" and called it a "turning point."

In a telephone interview, he said of Mr. Bush's statement: "We were unhappy with the initial actions of the American officials, because they were perceived by the Russians as green lines basically. But this one was very strong." "What I expected specifically from America was to secure our airport and to secure our seaports," he went on, concluding that the American presence would do so. "The main thing now is that the Georgian Tbilisi airport will be permanently under control."

In 2006, I made a serious error in judgment and conducted myself in a way that was disloyal to my family and to my core beliefs. I recognized my mistake and I told my wife that I had a liaison with another woman, and I asked for her forgiveness. Although I was honest in every painful detail with my family, I did not tell the public. When a supermarket tabloid told a version of the story, I used the fact that the story contained many falsities to deny it. But being 99 percent honest is no longer enough.

I was and am ashamed of my conduct and choices, and I had hoped that it would never become public. With my family, I took responsibility for my actions in 2006 and today I take full responsibility publicly. But that misconduct took place for a short period in 2006. It ended then. I am and have been willing to take any test necessary to establish the fact that I am not the father of any baby, and I am truly hopeful that a test will be done so this fact can be definitively established. I only know that the apparent father has said publicly that he is the father of the baby. I also have not been engaged in any activity of any description that requested, agreed to or supported payments of any kind to the woman or to the apparent father of the baby.

It is inadequate to say to the people who believed in me that I am sorry, as it is inadequate to say to the people who love me that I am sorry. In the course of several campaigns, I started to believe that I was special and became increasingly egocentric and narcissistic. If you want to beat me up feel free. You cannot beat me up more than I have already beaten up myself. I have been stripped bare and will now work with everything I have to help my family and others who need my help.

I have given a complete interview on this matter and having done so, will have nothing more to say.

If Edwards fails to clear up the story in short order, he risks party officials deciding not to have him speak or, if they do, creating a distraction from a week focused on Barack Obama accepting the nomination. "If there is not an explanation that's satisfactory, acceptable and meets high moral standards, the answer is 'no,' he would not be a prime candidate to make a major address to the convention," said Don Fowler, a former Democratic National Committee chair.

Democrats gather in Denver on Aug. 25 and Edwards, as the 2004 vice presidential nominee and a presidential candidate who won delegates this year, ordinarily would be locked in as a speaker. "He absolutely does have to (resolve it). If it's not true, he has to issue a stronger denial," said Gary Pearce, the Democratic strategist who ran Edwards' 1998 Senate race. "It's a very damaging thing. ...

"The big media has tried to be responsible and handle this with kid gloves, but it's clearly getting ready to bust out. If it's not true, he's got to stand up and say, 'This is not true. That is not my child and I'm going to take legal action against the people who are spreading these lies.' It's not enough to say, 'That's tabloid trash,' " Pearce said.

Edwards' political currency declines with each day the story goes unresolved, Fowler and other Democratic strategists said. An appearance at the convention would only highlight the unresolved story, said Chris Lehane, a Democratic consultant and former aide to then-Vice President Al Gore. A convention speaking appearance could become the moment that drives news media coverage of the alleged affair to explode. "You want to address these issues long before you get to that point," Lehane said. "Otherwise people who haven’t written about it before, now start writing about it."

Alaska Sen. Ted Stevens, at 84 the longest-serving Republican in the Senate and one of its most powerful members, was indicted Tuesday on seven felony counts alleging that he lied to conceal his acceptance of $250,000 in gifts and services from a now-defunct Alaska oil services and construction company.

Stevens notified senior Republicans that he'd abide by a Senate Republican rule and temporarily step down from his ranking posts on the Senate Commerce Committee and an Appropriations subcommittee.

The indictment, returned by a federal grand jury in Washington, charges that Stevens made false statements on his annual Senate financial-disclosure statements for the years 2001 through 2006 to conceal gifts from VECO Corp. and its chief executive officer, Bill Allen. If he's convicted, Stevens could face an unspecified fine and as much as five years in prison.

The indictment marked the latest turn in a sweeping, four-year-old federal investigation of public corruption in Alaska that already has led to seven convictions and also is focusing on veteran Republican Rep. Don Young. The investigation has revolved around VECO, whose executives have been the top donors to Alaskan political campaigns in recent years.
