Gov. Christie said Thursday that he would "reach out" to House Speaker Paul Ryan, after Ryan announced he was not ready to endorse Donald Trump in the presidential race.

"I'm going to reach out to the speaker and see what his concerns are," the Republican governor, who endorsed Trump not long after dropping out of the presidential race in February, said at a Statehouse news conference.

Of Ryan – who is also chairman of the Republican National Convention – declining to support Trump, Christie said that "Donald's got work to do to bring people together." But, he said, "That's not a whole lot different than primaries I've seen over my life."

Despite the departure of Trump's rivals from the race this week, some conservatives and GOP establishment figures are continuing to refrain from backing the billionaire. Both former Bush presidents aren't planning to participate in the race, spokesmen said Wednesday.

Asked Thursday about his early endorsement of Trump and "what that could mean for you down the line," Christie said: "Like, how do I go from being an idiot 68 days ago to prescient 68 days later? … I haven't given that a lot of thought."

"Donald's my friend, he's been my friend for 14 years," Christie said. "If he picks up the phone and calls and asks me to do something that I can do, to help his cause to be elected president, I'll do it. But it has to be consistent with my responsibilities here."

"I'll decide what's important, along with Donald," Christie said. But "there are no current requests pending from Donald."

To a question on controversial comments by Trump, Christie said he was "not going to judge every person that I associate with … by every comment they make."

"There's a lot of other things that I know about Donald Trump that I consider to be really admirable, really smart, and really compassionate," Christie said. "You either have to take my word for it, or not take my word for it."
