Speaker John Boehner says he intends to file a lawsuit accusing President Barack Obama of failing to carry out the laws passed by Congress.
The suit would be filed on behalf of the Republican-controlled House.
Boehner provided no details of the claims to be made in the suit. He privately briefed members of his rank and file on his plans on Tuesday.
Republicans have long accused Obama of selectively enforcing the health care law that bears his name, and doing the same with immigration legislation long on the books.
At his weekly news conference, the speaker said the Constitution makes it clear the president’s job is to faithfully execute the law.
