How much more evidence does Congress need to begin impeachment hearings?

Republicans in Congress are distancing themselves from the Bush Administration, which is sinking under the weight of lies and corruption. They could do the entire country a favor if they would simply begin impeachment hearings against what will go down in history as the most corrupt administration ever!

There is certainly enough evidence. And who knows, it might be a way for some of the more moderate Republicans to save their seats! We are now learning there is further evidence that the White House knew there were no WMD in Iraq.

Reuters is reporting:

The CIA had evidence Iraq possessed no weapons of mass destruction six months before the 2003 US-led invasion but was ignored by a White House intent on ousting Saddam Hussein, a former senior CIA official said, according to CBS.

There hasn't been this much evidence to justify impeachment since the Nixon administration.
