Excerpt:
US Rep. Johnson Joins 10 Others on Cheney Impeachment Bill
By Matthew Cardinale, News Editor, The Atlanta Progressive News (June 29, 2007)

(APN) ATLANTA – US Rep. Hank Johnson (D-GA-04) has joined ten other Members of Congress in supporting H Res 333, a bill to impeach Vice President Dick Cheney.

"I believe it was time to send a message to the Vice President and to the Executive Branch as a whole," Congressman Johnson told Atlanta Progressive News in a statement issued verbally by spokesperson Deb Speights.

"I have certainly been displeased with the operations of the Executive Branch, particularly with regard to the secrecy, the incompetence, and the lack of cooperation that is coming out of the Vice President’s Office. I think the response to [reject] the subpoenas was the last straw," Johnson said.

Johnson was one of three US Reps to join the bill yesterday, and the only Georgia Member to have signed on so far. Johnson’s predecessor, US Rep. Cynthia McKinney (D-GA), had been a strong supporter of impeachment, including, among other things, introducing her own Articles of Impeachment against President Bush at the end of her most recent term.

US Rep. Jim McDermott (D-WA) made a speech on the House Floor, “The Vice President Should Resign or Face Impeachment,” announcing his plans to support the bill. US Rep. Keith Ellison (D-MN) also joined yesterday.

The other total supporters include original sponsor, US Rep. Dennis Kucinich (D-OH), plus US Reps. Yvette Clarke (D-NY), William Lacy Clay (D-MO), Barbara Lee (D-CA), Janice Schakowsky (D-IL), Maxine Waters (D-CA), Lynn Woolsey (D-CA), and Albert Wynn (D-MD), so far.

US Rep. John Lewis (D-GA-05) had said on WAOK radio in December 2005 he would sign a bill to impeach President Bush should it come across his desk. Lewis has not signed on to this bill even though the misdeeds of Cheney cited in H Res 333 would equally apply to Bush..

Cynthia McKinney is the devil.
Get your shots in now, guys - she's already irrelevant.
Joe Lieberman should be the object of your disdain.

Wow, FOX News covered this harder than anyone.
I can't imagine why.
They must be bumming that they won't have Cynthia McKinney to kick around anymore.
