Minneapolis police 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 Monday, according to the Star Tribune.

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

Harteau and Stanek were invited as part of the Major Cities Chiefs Police 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 Newton, Conn., and Aurora, Colo.

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 for his proposed gun-control legislation.

Obama unveiled his gun proposal Jan. 16 and included in it a ban on military-style assault weapons and a requirement of universal background checks on gun owners.
