MILFORD, N.H.—New Jersey Gov. Chris Christie condemned President Obama’s diplomatic deal with Iran, calling it the biggest mistake of his presidency.

“Everything he’s done before last Tuesday is minor league compared to the gravity of this mistake,” Christie said at a town hall meeting.

The Republican presidential candidate said that Obama’s remarks surrounding the deal will become known as “the big lie of the second term.”

“He said we have anytime, anywhere access to the key nuclear sites in Iran,” Christie said. “That’s completely untrue.”

“If we catch them doing something, we have to wait 24 days,” Christie continued. “Is that anytime, anywhere?”

The “big lie of the first term,” he said, is “If you like your doctor, you can keep your doctor. If you like your insurance plan, you can keep it.”

“The big lie of the second term is, ‘We can inspect nuclear facilities in Iran anytime, anywhere,’” Christie said.

Christie said that America must be “the world’s leader” rather than “the world’s police,” and that “American strength prevents violence.”

Christie also discussed his pro-life views, after he was asked by an audience member about his thoughts on human life in light of the scandal surrounding Planned Parenthood.

Earlier this week, the Center for Medical Progress released a video of Dr. Deborah Nucatola, the senior director of medical services at Planned Parenthood, discussing the sale of fetal organs at affiliates of the organization. Planned Parenthood said in a statement that the “heavily edited, secretly recorded videotape … falsely portrays Planned Parenthood’s participation in tissue donation programs that support lifesaving scientific research.”

“This is an awful thing,” Christie said. “And it confirms some of the worst suspicions that people have about that organization.”

Christie said that he “vetoed funding for Planned Parenthood out of the budget in New Jersey for the last six years.”

He called for a “comprehensive and deep investigation” into the allegations against the nation’s largest abortion provider.

“The president of Planned Parenthood has come out and apologized for the tone,” Christie said. “Apologizing for the tone of the woman in the video. I think we need to know a little bit more than that.”

Christie said he wants his party to be “pro-life for the entire life.”

“I’m pro-life,” Christie said. “The fact is that I’m the first person since Roe v. Wade in New Jersey to get elected as a pro-life person.”

Christie said he was discouraged from discussing his pro-life views while running for governor of a blue state, “but I ran as an unapologetic, pro-life person.”

“Here’s what I said to folks: It’s what I believe,” Christie said.

Christie said he will lead as a person “with respect for the sanctity of human life.”

Christie stressed that a pro-life position should also encompass making drug addiction treatment programs more readily available and opposing legalized assisted suicide.
