Colorado Senator Ken Salazar says he won't try to block the confirmation of Judge Samuel Alito to the Supreme Court.
Salazar says he still plans to vote against President Bush's pick to succeed retiring Justice Sandra Day O'Connor.
He is troubled by Alito's positions on civil rights and presidential power.
But he says he is convinced he should not filibuster because Alito has a stellar academic record and strong support from his colleagues.
Senators are debating Alito's confirmation today. Almost all the Democrats plan to vote against him.
Salazar says he doesn't know whether other Democrats will try to block the vote. He says if they do, he will call a meeting of the Gang of 14.
Last year, that group prevented a showdown between Republicans and Democrats in the Senate over Bush's judicial appointments.
