DENVER (AP) — Colorado Democratic Sen. Mark Udall says supporters of universal background checks for gun buyers aren’t giving up despite a defeat in the Senate.

Udall predicted Thursday that public pressure for background checks will grow. He says supporters see the Senate vote as only a temporary setback.

Fifty-four senators voted for background checks Wednesday, but a 60-vote majority was required for passage by agreement of Senate leaders.

Udall voted for the background-check measure, saying it would have helped keep firearms out of the hands of people who shouldn’t own them.

He also voted for a measure to limit the number of bullets a magazine can hold. It also failed.
