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.” …

“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.” …

“When you’ve got 90 percent of the American people supporting the initiatives that we put forward … I believe that eventually we’re going to get that done, and I’m going to keep on trying,” he said.
