President Obama is in Colorado Wednesday, pushing new federal gun control measures.
The president is calling for universal background checks. He also wants Congress to at least vote on an assault weapons ban and limits on high-capacity magazines.
"We are working with lawmakers of both parties and trying to achieve a compromise that can make this happen, especially when it comes to the background checks," White House press secretary Jay Carney told reporters Tuesday.
The president's trip comes a day after the National Rifle Association released a study that says at least one adult in every school should be armed with a gun and know how to use it.
