The Miami Republican and chair of the House Foreign Affairs Committee is siding with other congressional Republicans who say President Barack Obama needs to better define U.S. goals in Libya.
"The United States has and always should stand with those who are oppressed and denied their fundamental freedoms," she said in a statement. "However, that cannot be the only criteria on which we base U.S. military involvement.
"I am concerned that the President has yet to clearly define for the American people what vital United States security interests he believes are currently at stake in Libya. We need to know what the President believes ultimately must be accomplished in Libya to protect and advance U.S. interests there.
"The American people expect the President, as our Commander in Chief, to determine when U.S. national security interests are at risk and what he is prepared to command the men and women of our Armed Forces to undertake in order to protect and defend them. Deferring to the United Nations and calling on our military personnel to enforce the 'writ of the international community' sets a dangerous precedent.
"In assessing U.S. security interests and objectives, the President must also keep in mind Qaddafi's attacks on Western targets resulting in the deaths of Americans in the 1980s."
