It took two years, but it finally happened - thanks to an agreement with the White House that deposing Rove would not infringe on executive privilege. Now everyone wants to know: What did Karl say? And don't you wish you were the fly on the wall?

Former White House Deputy Chief of Staff Karl Rove was deposed Tuesday by attorneys for the House Judiciary Committee, according to Rep. John Conyers (D-Mich.), the panel’s chairman.

Rove’s deposition began at 10 a.m. and ended around 6:30 p.m, with several breaks, Conyers said.

Conyers would not comment on what Rove told congressional investigators, what the next step in the long-running Judiciary Committee investigation would be or whether Rove would face additional questioning.

“He was deposed today,” Conyers said in an interview. “That’s all I can tell you.”

Rove's attorney, Robert Luskin, declined to confirm or deny that his client had appeared before the committee. Luskin said there was an agreement that the depositions would remain confidential until they were completed. However, in a court filing Monday, the Justice Department indicated that the deposition set for this week would be the committee's last.

Conyers’ panel had first subpoenaed Rove in 2007 as part of its probe into the firing of nine U.S. attorneys. But the Bush White House, citing executive privilege, refused to make Rove or White House Counsel Harriet Miers available for any deposition.

(The Shoes of Billy Sol Estes - no doubt the Alligator had other plans.)

What had to be one of the biggest scandals of the 1960's centered around one Billy Sol Estes whose influence and fraud wandered through many high places in Washington, allegedly all the way up to the office of Lyndon Johnson. Estes was the subject of a Senate Sub-committee investigation on political corruption which led to a startling number of discoveries and an even more startling number of "suicides" in the process. Although Estes was convicted of fraud and corruption charges and sentenced to prison, his conviction was overturned by a Supreme Court decision that ruled the massive amount of publicity the investigation garnered made a fair trial impossible.

Still, the allegations were serious enough about LBJ to force Kennedy to consider dropping him as running mate in 1964. And he probably would have, had fate not intervened.

On July 2, 1962, at the height of the investigation, ABC's long-running Sunday talk show Issues and Answers featured a dialogue between Texas Attorney General Will Wilson and Senator Edmund Muskie, who was a member of the Senate Subcommittee investigating the Estes scandal.
