The Tennessean newspaper is reporting that Al Gore is poised to endorse Barack Obama at a news conference Wednesday:

Former Vice President Al Gore’s office confirms that he will endorse Democratic Senator Barack Obama tomorrow morning. The Senator from Illinois was able to secure the much sought after endorsement on a telephone call with the Vice President last night.

The Politico reports on the reaction from Hillary Clinton’s campaign:

On a just concluded conference call, Clinton campaign’s chief strategist Mark Penn dismissed the Gore endorsement. He said, "it is long past the time when this endorsement would be considered significant. Al Gore represents the pre-9/11 way of thinking. It will make no difference to our campaign. We are in it to win it."

Later in the call, Howard Wolfson added, "we have the greatest respect for the Vice President. We think it is a fine vice presidential endorsement."

CNN was able to get reaction from some prominent Clinton surrogates:

Clinton supporter James Carville was dismissive of the endorsement. Reached by phone at his home, he unapologetically said, "I think he is Judas. He betrayed the Clintons. Hillary Clinton made him the man he is today. Hillary introduced him to the Internet and gave him the global warming slides. He is disloyal. I mean it." He then added before hanging up the phone, "I am mad as hell. I am going to write all about this Judas in an op-ed on the Pttsburgh-Tribune Review."

Geraldine Ferraro, prominent Clinton supporter, told the Daily Breeze, "Barack Obama is lucky to get this endorsement. It only proves my point. If Obama was a white man or a white woman, Al Gore would not have endorsed him. This endorsement clearly shows how lucky he is."

Lanny Davis told CNN’s Anderson Cooper that he was disappointed with the endorsement. He said that he had "two questions" for Al Gore that he would later post in a blog on the Huffington Post.

Asked about the national security implications of Al Gore’s endorsement, terrorism expert Larry Johnson said that it was troubling to see Al Gore endorse Ice Cube. He said that having gangstas in the White House would pose serious national security risks.

Hillary Clinton was unavailable for comment.

ABC News is reporting that Attorney General Alberto Gonzales will resign this evening. ABC is also reporting that the White House has requested time on the major networks for a presidential address for 9pm Eastern tonight.

According to ABC News:

Sources in the White House tell ABC News that Alberto Gonzales will resign this evening. Shortly thereafter, the president will address the nation at prime time. There is speculation within the White House that the president will also ask some of his senior advisors to resign. Earlier today White House Chief of Staff Josh Bolten was observed entering the White House with other staff members to attend what appeared to be a hastily organized meeting.

Attempts to contact the Justice Department and the Attorney General for comment were unsuccessful.

The Washington Post is also reporting that the White House search for a replacement for Alberto Gonzales has been successful. It is likely that the President will announce the replacement during his prime time speech tonight:

The White House has been searching since the U.S. attorneys scandal broke earlier this month for a suitable candidate to replace the current attorney general, Alberto Gonzales. Late last week, sources tell the Washington Post, White House Chief of Staff Josh Bolten presented President Bush with three names on a "short list" of candidates. The names on the list are reported to be Solicitor General Theodore Olson, United States Attorney for the Northern District of Illinois Patrick Fitzgerald, and former United States Marine and interim United States Attorney for the Southern District of California Rod Majors. Multiple sources within the Oval Office have told the Washington Post that the president will nominate Rod Majors to replace Alberto Gonzales as the next attorney general.

While a Sunday announcement is unusual, it has long been rumored that Alberto Gonzales will step down. This week’s testimony of his chief-of-staff highlighted the many inconsistencies in Mr. Gonzales’s recent statements regarding Gonzogate. I hope the president moves quickly for a Senate confirmation for Mr. Majors.

I look forward to a scandal-free next two years at the Department of Justice. I hope you the reader join me in that hope. Let us all give Mr. Majors our full support as he leads the Department of Justice and this nation out from this sticky situation.
