Texas Republican Rep. Steve Stockman threatened Monday afternoon that he would file articles of impeachment against President Barack Obama if he institutes gun control measures with an executive order.
Stockman warned that such executive orders would be “unconstitutional” and “infringe on our constitutionally-protected right to keep and bear arms.”
“I will seek to thwart this action by any means necessary, including but not limited to eliminating funding for implementation, defunding the White House, and even filing articles of impeachment,” Stockman said in a statement.
At his press conference Monday, Obama floated the possibility  of using executive action to enact policies aimed at reducing gun violence.
