That move is certain to "increase the angry reaction from Republicans" who already accuse Obama of exceeding his executive authority, Pfeiffer said, highlighting recent statements by former vice presidential candidate
"I would not discount the possibility" that Republicans would seek to impeach Obama, he said, adding that House Speaker
Many strategists in both parties believe that Republicans suffered serious political damage during the 1990s from impeaching President Clinton over making false statements in connection with his affair with Monica Lewinsky. The impeachment then crystallized the public view of the GOP as intransigent and overly political, polls indicated.
"The Republican party will have a choice," he said, of either repudiating those factions in the party that strongly oppose any legal status for those who are currently undocumented or running a campaign saying "elect a Republican to deport all these people."
Boehner repeatedly has ruled out calls for impeachment proceedings that have come from a variety of more conservative Republicans and has pushed back against those in the party who have stirred the effort. His proposal for a lawsuit alleging that Obama has exceeded his powers has been widely seen as an effort to tamp down those discussions.
Republican aides see Pfeiffer's comments as an attempt to excite Democratic activists and donors in the roughly 100 days remaining before the midterm elections.
"We have a humanitarian crisis at our border, and the White House is making matters worse with inattention and mixed signals," said Boehner spokesman Michael Steel. "It is telling, and sad, that a senior White House official is focused on political games, rather than helping these kids and securing the border."
