Rep. Jim Jordan (R-Ohio) officially announced Wednesday that he will challenge Rep. Kevin McCarthy (R-Calif.) for House minority leader.

Why it matters: Jordan, the founder of the conservative House Freedom Caucus, told his colleagues in July that he was running to replace Paul Ryan as Speaker of the House. McCarthy has Ryan's endorsement and is a close confidant of President Trump, though conservative leaders have argued in a letter obtained by Axios that Jordan is the solution to "failed" Republican leadership, which has "proven that it’s part of the Swamp."
