Oooh, nuance!

"I have said I won't even wait until I'm inaugurated, but as soon as I'm elected I'm going to be asking distinguished Americans of both parties -- people like Colin Powell, for example -- and others who can represent our country well, including someone I know very well," Clinton told the predominantly black audience after receiving the endorsement of dozens of South Carolina ministers.

Contacted by ABC News' Teddy Davis, Gen. Colin Powell was tight-lipped Tuesday when asked if he is open to Clinton's invitation.

"I have not seen what she has said. I don't know the context of it," Powell told ABC News. "I have admiration for Mrs. Clinton but I have no comment."

WASHINGTON (CNN) -- Sen. Trent Lott, R-Mississippi, intends to resign by the end of the year and join the private sector, sources tell CNN.

Lott is expected to make the announcement Monday in Pascagoula, Mississippi.

A senior Republican source close to Lott said one reason for the decision is the new lobbying restrictions on former lawmakers.

A law kicks in on January 1 that forbids lawmakers from lobbying for two years after leaving office. Those who leave by the end of 2007 are covered by the previous law, which demands a wait of only one year.

Lott, the Republican whip, was elected last year to a fourth term in the Senate. His term lasts until 2012.

As they say ... Breaking News from the Senate.

Forgive me if some of this is in the weeds, I'll try and make the parliamentary process as painless as possible.

1. Within the last hour, the Senate Judiciary Committee just reported out a FISA bill that DOES NOT include retroactive immunity for the telecom companies that helped the Bush Administration spy on Americans.
2. This means the Judiciary bill moves to the full Senate WITHOUT the dangerous language included.
3. Retroactive immunity will, however, surely be introduced as an amendment to the FISA bill.
4. If needed Senator Dodd will filibuster any amendment seeking to add retroactive immunity to the underlying bill. By filibustering, he will force the opposition to find 60 votes to pass the provision.

It will be a lot more difficult for those who would enable the erosion of our Constitution to find the 60 votes necessary to stop immunity on its own than it would be for us to find the 40 needed to sustain a filibuster of the bill as a whole if it included immunity.

Today is a great victory for all of us -- and another example of Chris Dodd's leadership.

If it wasn't for our efforts, together, retroactive immunity would be well on its way to sailing through the Senate ... largely unnoticed.

The Justice Department has reopened a long-dormant inquiry into the government's warrantless wiretapping program, a major policy shift only days into the tenure of Attorney General Michael Mukasey.

The investigation by the department's Office of Professional Responsibility was shut down last year, after the investigators were denied security clearances. Gonzales told Congress that President Bush, not he, denied the clearances.

"We recently received the necessary security clearances and are now able to proceed with our investigation," H. Marshall Jarrett, counsel for the OPR, wrote to Rep. Maurice Hinchey, D-N.Y. A copy of the letter, dated Tuesday, was obtained by The Associated Press.

Hinchey and other Democrats have long sought an investigation into the spying program to see if it complies with the law. Efforts to investigate the program have been rebuffed by the Bush administration.

"I am happily surprised," Hinchey said. "It now seems because we have a new attorney general the situation has changed. Maybe this attorney general understands that his obligation is not to be the private counsel to the president but the chief law enforcement officer for the entire country."

WASHINGTON - Barack Obama sparked a generational fight Wednesday by trashing White House rival Hillary Clinton for being too old to unite America, saying she and others her age have fought the same tired fights for too long.

"I think there's no doubt that we represent the kind of change that Sen. Clinton can't deliver on, and part of it is generational," Obama, 46, said on Fox News. "Sen. Clinton and others, they've been fighting some of the same fights since the '60s, and it makes it very difficult for them to bring the country together to get things done."

Experts and opponents pounced, saying Obama's remarks could offend the most reliable voters, people older than 50 - especially in early-voting Iowa. "You are counting precisely on an older group of Democrats in Iowa," said Iowa State University's Steffen Schmidt. "You can't tell them they're backward-looking. Somebody should be fired in his campaign."

To the Chairman and Members of the Judiciary Committee,

If you are really interested in stopping the bombing of Iran, you will consider this impeachment resolution without delay. There is nothing more important than stopping the lawless warmongering of this out-of-control Executive.

Thank you.

Thirty US senators wrote to President George W. Bush Thursday, warning he had no authority to launch military action against Iran, and expressing concern about the administration's "provocative" rhetoric.

The senators, 29 Democrats and one independent, urged the resolution of disputes with the Islamic Republic through diplomacy.

"We wish to emphasize that no congressional authority exists for unilateral military action against Iran," the letter signed by senators including presidential candidates Hillary Clinton and Joseph Biden said.

The letter warned that a resolution passed by the Senate in September, calling for the designation of Iran's Revolutionary Guard Corps as a terrorist group, should not be used as a pretext for war.

It hit out at "provocative statements and actions" by the administration on Iran, after Bush last month warned Tehran must be barred from nuclear weapons to avoid the prospect of "World War III."

"These comments are counterproductive and undermine efforts to resolve tensions with Iran through diplomacy," the letter, coordinated by Virginia Senator Jim Webb, said.

The White House plans to try implementing as much new policy as it can by administrative order while stepping up its confrontational rhetoric with Congress after concluding that President Bush cannot do much business with the Democratic leadership, administration officials said.

White House aides say the only way Bush seems to be able to influence the process is by vetoing legislation or by issuing administrative orders, as he has in recent weeks on veterans' health care, air-traffic congestion, protecting endangered fish and immigration. They say they expect Bush to issue more of such orders in the next several months, even as he speaks out on the need to limit spending and resist any tax increases.
