WASHINGTON -- Senate Majority Leader Harry Reid (D-Nev.) likely has the votes on gun control legislation to clear its first procedural hurdle -- a victory for the gun control community, though one that hardly guarantees the bill's passage.

The majority leader announced on Tuesday evening he would submit for a vote the bill to expand background checks, implement a federal trafficking statute and enhance school safety measures. That would set up a Senate vote on Thursday. To help push matters along, President Barack Obama was spending Tuesday calling senators to lobby them on the gun measures, a White House official confirmed. The official did not reveal which senators would be receiving calls.
