WASHINGTON — Speaker Paul D. Ryan said in a series of televised interviews on Sunday that he would not work with the Obama administration on changing immigration policy, effectively pushing off the issue to at least 2017.

“Look, I think it would be a ridiculous notion to try and work on an issue like this with a president we simply cannot trust on this issue,” Mr. Ryan, Republican of Wisconsin, said in an interview with CBS’s “Face the Nation.” “He tried to go it alone, circumventing the legislative process with his executive orders, so that is not in the cards.”

The message from Mr. Ryan, who was elected speaker on Thursday, signaled an antagonism toward the White House that both echoed his predecessor, John A. Boehner, and is likely to appeal to the party conservatives who forced Mr. Boehner’s resignation.

Mr. Ryan taped five Sunday morning news shows, in which he laid out his agenda for unifying his party and his approach to relationships with congressional colleagues, Mr. Obama and Republican presidential candidates.
