WASHINGTON (AP) — President Barack Obama kept up pressure on Congress Monday to pass tough new gun legislation, seeking help from law enforcement leaders in three communities that have suffered the horrors of mass shootings.

At a White House meeting, Obama said that no group is more important in the gun debate and he said he recognizes the issue "elicits a lot of passion all across the country." But Obama also said he believes Congress will respond to appeals from police.

"Hopefully if law enforcement officials who are dealing with this stuff every single day can come to some basic consensus in terms of steps that we need to take," he said, "Congress is going to be paying attention to them, and we'll be able to make progress."
