The notion of impeaching President Barack Obama got substantial attention Friday from two White House officials, who both said senior Republicans wanted to see it happen. But they couldn’t name any senior Republicans when pressed.

Further, White House press secretary Josh Earnest expressed doubt about whether House Speaker John Boehner (R-Ohio) was sincere when he said impeachment is not on the table.

“I do believe that the speaker said on a number of occasions that there would not be steps taken by Republicans to shut down the government over health care,” Earnest said of Boehner, adding, “Maybe you need to ask him a little bit more about whether impeachment is on the table or not.”

Some conservatives have called for impeaching Obama regarding executive overreach on issues such as Obamacare, immigration and guns without congressional authorization. The Democratic National Committee and Organizing for America have consistently used impeachment in fundraising emails to warn donors about what could happen if Republicans win more seats in the House and gain control of the Senate.
