WASHINGTON, D.C.(KELO)- It’s the modern day political version of the showdown at the OK corral.

Senator John Thune called Democratic Minority Leader Chuck Schumer’s bluff by calling for a vote on a measure to fund the government until the end of September.

Failure to pass the measure would mean a partial government shutdown tonight.

Senator Mike Rounds appeared with Greg Belfrage this morning, offering praise for Senator Thune’s handling of the matter.

The Senate vote is scheduled to take place early this afternoon.
