House Speaker John Boehner confirmed to Fox News on Wednesday that Republicans will sue President Obama over his use of executive action on immigration.

“The president’s overreach when he took executive action to deal with the immigration problems in our country, frankly, in my view, is a violation of our Constitution,” Boehner said on “Special Report with Bret Baier.”

“We believe that the filing of a lawsuit to try to stop the president from – from violating our Constitution is an important step for our institution,” he added. “This isn’t about immigration. This is the president violating the Constitution, violating his oath of office, and frankly, not upholding the rule of law.”
