( NewsNation) — U.S. Rep. Mike Johnson, R-La., will run for a second term as Speaker of the House, he announced in a letter to colleagues Wednesday, although party control of the chamber remains uncalled.

Louisiana voters send Speaker Mike Johnson back to the House, where his next challenge will be to keep the top job there if Republicans hold the majority.

House Speaker Mike Johnson has served in the post for little over a year, but his tenure has been marked with few legislative accomplishments and a series of splits within his conference that stymied his party’s agenda.

House Majority Leader Steve Scalise (R-La.) and House Majority Whip Tom Emmer (R-Minn.) formally asked House Republicans to reelect them to their leadership posts in letters sent to GOP members on Wednesday and Thursday.
