Newly-elected House Speaker Paul Ryan, R-Wis., said Sunday that it "would be a ridiculous notion" to work with President Barack Obama on his unilateral immigration reform.

Obama announced his executive immigration action, sometimes referred to as amnesty, last November. It would allow as many as 4.7 million illegal immigrants to stay in the country without threat of deportation, but has been placed on hold by the courts until a lawsuit filed by 26 mostly conservative states can be decided.

Ryan, who was chosen as speaker on Thursday and has previously supported immigration reform, told CBS' "Face the Nation" on Sunday that he thinks "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," reported Reuters.

"He tried to go it alone, circumventing the legislative process with his executive orders, so that is not in the cards," Ryan said.

"I think if we reach consensus on how best to achieve border and interior enforcement security, I think that's fine," he added.

Ryan also said he is prepared to "take some policy risks" and show "the people what we really believe, who we are, and how we can fix this country's great problems."

Those policy risks will include tackling the bloated tax code and replacing Obama's signature 2010 health care law, often referred to as Obamacare.

"I think we should say what Obamacare replacement looks like," Ryan said. "People don't like Obamacare."

Ryan also appeared on CNN's "State of the Union" on Sunday, telling host Dana Bash that he plans to reform how legislation is proposed in the House and ensure that all members of Congress have an equal and fair opportunity to get their amendments considered, reported The Washington Times.

"I think members are frustrated that they didn't have the opportunity to discuss their views on the floor," he said, adding that the process is currently "too controlled."

A Planned Parenthood investigation is also likely to occur under Ryan's leadership, and he said that he will try end federal funding for the group as well. Republicans have been attempting to shutter the group since the release of secretly recorded videos showing employees discussing payments for selling fetal tissue to medical researchers.

"I don't think Planned Parenthood should get a red cent from the taxpayers," Ryan said. "I believed that before these disgusting videos came out."

He said that he will create a special committee to investigate Planned Parenthood, similar to the committee set up by former Speaker John Boehner to investigate the 2012 terrorist attacks in Benghazi, Libya.
