Minneapolis Chief Janeé Harteau and Hennepin County Sheriff Richard Stanek were among the 13 law enforcement officials invited to the White House to discuss gun control on Monday, according to the Star Tribune.

President Barack Obama, Vice President Joe Biden, Attorney General Eric Holder, and Homeland Security Secretary Janet Napolitano Monday were all in attendance at the meeting.

Chief Harteau and Sheriff Stanek were invited as part of the Major Cities Chiefs Association and the Major County Sheriffs Association, according to CBS News. The president invited police from cities that have recently suffered through a high-profile mass shooting, such as Newtown, Connecticut and Aurora, Colorado. 

However, Obama is also committed to fighting urban gun-violence in addition to mass shootings, according to CBS News.

This meeting represents the latest installment of Obama’s push for tighter gun control across the country, according to Reuters. Outspoken support from law enforcers would help the president rally the support he needs in Congress to support his proposed gun control legislation.

Obama’s gun proposal was unveiled on January 16, according to a White House press release. The proposal included a ban on military-style assault weapons and universal background checks on gun-owners.
