In March 2011, Kucinich criticized the Obama administration's decision to participate in the UN intervention in Libya without Congressional authorization. He also called it an "indisputable fact" that Obama's decision was an impeachable offense since he believes the U.S. Constitution "does not provide for the president to wage war any times he pleases", but he did not introduce a resolution to impeach Obama. In response, Libyan officials invited Kucinich to visit that country on a "peace mission", but he declined, saying that he "could not negotiate on behalf of the administration."
