As the flames of war burn in the Middle East and Ukraine, the U.S. Congress is immobilized by a brawl among Republicans, a dysfunction that even some in Donald Trump's party worry is giving comfort to the nation's adversaries.

The House of Representatives has drifted leaderless for 12 days since eight of its 221 Republicans ousted Speaker Kevin McCarthy. That has held up any legislative action, from debating further aid to Ukraine as it battles a Russian invasion to a statement of support for ally Israel in its war with Hamas.

Republicans on Friday nominated hardliner Jim Jordan for speaker, but it was not clear if the longtime antagonist of party leadership would have the support needed to win a floor vote this week.

McCarthy’s removal was the latest in a series of self-created crises Congress has faced in a year that saw lawmakers bring the federal government to the brink of defaulting on its $31.4 trillion in debt and just two weeks ago narrowly avert the fourth partial U.S. government shutdown in a decade.

That latter move led to McCarthy’s ouster by colleagues angry that the spending bill passed with more Democratic than Republican votes, even though any measure passed by the House needs to clear the Democratic-controlled Senate and be signed by Democratic President Joe Biden to become law.

Some House Republicans voiced frustration and anger that they have gone so long without being able to choose a leader.
