Days after saying that President Obama’s authorization of U.S. intervention in Libya is an “impeachable offense,” Rep. Dennis Kucinich (D-Ohio) is now using his criticism of the president in a fundraising appeal.

Kucinich posted a video message on his campaign Web site Monday in which he asks supporters for campaign contributions and charges that the Obama administration’s decision to intervene in Libya was “outside the Constitution of the United States.”

“Whether you like President Obama or not is not the question,” Kucinich says in the message. “The question is: if you like the Constitution more. And the Constitution places very firmly in the hands of Congress the decision as to whether or not to commit the men and women of our armed services to a conflict, or the physical assets of the United States of America into a conflict.”

Kucinich also announced Tuesday that he plans to offer an amendment to an upcoming spending bill that “would prohibit funding for U.S. involvement in military operations in Libya.”

Kucinich’s video message appears to be the first instance of a candidate making mention of the Libya conflict in a fundraising appeal. Members of both parties have been stepping up their criticism of Obama on the conflict, arguing that Congress should have played a greater role in the decision-making process. None, though, has gone as far as Kucinich in suggesting that Obama should face impeachment.

The video comes as Kucinich, who is up for a ninth term in 2012, faces the prospect of having his district redrawn in Ohio’s redistricting battle, which will see the Buckeye State lose two House seats. Faced with the prospect of a tough bid, the Ohio Democrat has already made forceful fundraising pleas to his supporters; as he has in those previous messages, Kucinich notes in his most recent fundraising missive that his district may be “dramatically altered” and that he’s “going to have to make some decisions about where I’m going to run.”

In the video, Kucinich also reiterates his longtime opposition to the war in Iraq and mentions his recent symbolic resolution on pulling troops out of Afghanistan.

The measure was rejected by the House last week but garnered the support of 93 members. Kucinich notes in his message that he “forced a vote once again” on Afghanistan “and got more support than ever for Members of Congress to put themselves on the line with their votes to say, ‘let’s get out.’”
