TOPEKA, Kan. (AP) — The U.S. Senate is moving toward a vote on Kansas Gov. Sam Brownback's nomination for an ambassador's post.

Senate Majority Leader Mitch McConnell filed a motion Monday to cut off debate on President Donald Trump's nomination of the conservative Republican governor to serve as U.S. ambassador-at-large for international religious freedom.

McConnell communications director David Popp said in an email that a vote on the motion would occur Friday unless minority Democrats agree to have a vote sooner. Ending debate would clear the way for a second vote on Brownback's nomination.

Trump first nominated Brownback for the ambassador's post in July, but his appointment has faced opposition from Democrats and LGBT groups.

Brownback would resign if he is confirmed. Fellow Republican Lt. Gov. Jeff Colyer would be elevated to governor.
