Republican leaders in the U.S. House unanimously voted to remove Iowa Congressman Steve King from House committees — a decision King immediately denounced.

King had been a member of the Agriculture and Small Business Committees as well as the powerful House Judiciary Committee. House Republican Leader Kevin McCarthy said stripping King of his committee assignments shows King’s remarks about white supremacy “will not be tolerated” in the GOP. King, in a written statement, said removing him from committees was “a political decision that ignores the truth.” King says the remark he made to The New York Times has been mischaracterized.

The Republican leader in the U.S. Senate also weighed in yesterday. Senate Majority Leader Mitch McConnell of Kentucky said if King doesn’t understand why white supremacy is offensive, “he should find another line of work.”
