From the NY Daily News:
Rumors that Lieberman, D-Conn., could replace Rumsfeld started flying early this week, and Bush and Vice President Dick Cheney fanned the flames by quoting the former Democratic vice presidential candidate's pro-war statements.
The mention of Lieberman's name prompted some Democrats to whisper that he is lobbying for the job.
"Lieberman seems to be coordinating his statements on the war with the White House," a Senate Democratic source said.
The source pointed to a news conference this week where Lieberman urged his party not to undermine Bush. The timing of Lieberman's pitch, also this week, to form a bipartisan "war cabinet" to aid Bush was cited as well.
But Lieberman and Team Bush dismissed the rumors.
"The U.S. Senate is where Sen. Lieberman wants to be, which is why he is actively campaigning for re-election to his fourth term," the senator's spokeswoman, Casey Aden-Wansbury, said.
"That's funny," an administration official said.
