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.
Udall voted against a ban on assault weapons, saying it would have covered some hunting rifles and shotguns. That measure also failed.
