Presidential appointees will not be able to slide right into senior civil service jobs under a bill sponsored by Colorado Republican U.S. Rep. Ken Buck.

The practice is called "burrowing." A handful of appointees take advantage of it every time the White House changes hands.

Buck says his goal is to keep unqualified people out of high positions "so that people who have spent their lifetime working up through the ranks don't get demoralized because they see somebody with much less experience try to move into a senior career position."

Buck's bill is on track toward a House floor vote. The measure has bipartisan cosponsors, including Colorado Democrat Jared Polis.
