WASHINGTON – Rep. Dennis Kucinich (D-OH) on Tuesday announced that he will offer a measure to deny funds to the Obama administration for military attacks against Libya aimed at protecting civilians and ousting tyrant Muammar Gaddafi.

"I intend to offer an amendment to the forthcoming Continuing Resolution or Omnibus Appropriations bill that would prohibit funding for U.S. involvement in military operations in Libya," Kucinich wrote in a letter to colleagues. "I urge you to support this amendment."

The anti-war Democrat insisted that the Libya intervention being waged by the U.S., Britain and France is "act of war." He warned that the mission will be costly and could turn into a quagmire.

Kucinich will find support among similarly skeptical members of Congress, but gaining the necessary votes to block funding would be a tough climb as both Democratic and Republican leaders have thrown their support behind the Libya mission.

After raising the specter of President Barack Obama's impeachment in a private call with Democrats this weekend, Kucinich on Monday told Raw Story that Obama's decision to intervene without Congress's approval "would appear on its face to be an impeachable offense," claiming he violated the Constitution.

Numerous legal experts argue that Obama acted within his authority.
