A hard-core group of liberal House Democrats is questioning the constitutionality of U.S. missile strikes against Libya, with one lawmaker raising the prospect of impeachment during a Democratic Caucus conference call on Saturday.

Reps. Jerrold Nadler (N.Y.),
Donna Edwards (Md.),
Mike Capuano (Mass.),
Dennis Kucinich (Ohio),
Maxine Waters (Calif.),
Rob Andrews (N.J.),
Sheila Jackson Lee (Texas),
Barbara Lee (Calif.) and Del.
Eleanor Holmes Norton (D.C.)
ďall strongly raised objections to the constitutionality of the presidentís actionsĒ during that call, said two Democratic lawmakers who took part.

Kucinich, who wanted to bring impeachment articles against both former President George W. Bush and Vice President Dick Cheney over Iraq ó only to be blocked by his own leadership ó asked why the U.S. missile strikes arenít impeachable offenses.

Kucinich also questioned why Democratic leaders didnít object when President Barack Obama told them of his plan for American participation in enforcing the Libyan no-fly zone during a White House Situation Room meeting on Friday, sources told POLITICO.
