WASHINGTON — President Obama will go ahead with a “very significant” executive action on immigration after the summer – a move that may well trigger impeachment proceedings against him, senior Obama adviser Dan Pfeiffer told reporters at a Monitor breakfast Friday.
“The president acting on immigration reform will certainly up the likelihood that [Republicans] would contemplate impeachment at some point,” said Mr. Pfeiffer, who has been at the Obama White House since its inception.
A lot of people in Washington laughed off Sarah Palin’s call to impeach the president for executive overreach, Pfeiffer said, but “I would not discount that possibility.” Polling shows strong support for the idea among the GOP base, he said, adding that House Speaker John Boehner (R) of Ohio has opened the door to the possibility with his lawsuit against Obama.
