President Barack Obama vowed Thursday during a trip to Mexico to continue pushing for new, tighter gun control rules in the United States, saying his proposals’ recent defeat in Congress was “just the first round.”
Speaking following a meeting with Mexican President Enrique Peña Nieto, whose country has been ravaged by gang violence supported in part by gun trafficking into Mexico, Obama vowed to return to the issue of gun control in the United States.
“The last time we had major gun legislation, it took 6, 7, 8 tries to get passed,” Obama said at a press conference following his meeting with the Mexican president. “Things happen somewhat slowly in Washington, but this is just the first round.”
Democratic leaders in the Senate were forced to shelve a bipartisan proposal expanding background checks for firearms sold online and at gun shows when it failed to receive the requisite 60 votes to survive a filibuster threat. The measure’s Democratic proposal, West Virginia Sen. Joe Manchin, has vowed to fight to bring that proposal back up for another vote.
