Republican presidential candidate Donald Trump was unfazed on Thursday night by House Speaker Paul Ryan, who told CNN in an interview he is “not yet ready” to support Trump for president.

“I am not ready to support Speaker Ryan’s agenda. Perhaps in the future we can work together and come to an agreement about what is best for the American people,” Trump said in a statement posted on his website.

“They have been treated so badly for so long that it is about time for politicians to put them first!” he added.

Ryan had said in the CNN interview when asked about supporting Trump that he was “just not ready to do that at this point. I’m not there right now.”

He added he hopes to eventually back Trump and “to be a part of this unifying process.” The first moves, though, must come from Trump, he said.

Ryan said he wants Trump to unify “all wings of the Republican Party and the conservative movement” and then run a campaign that will allow Americans to “have something that they’re proud to support and proud to be a part of.”

Ryan has expressed misgivings about Trump’s campaign for months.

When Trump proposed indefinitely banning Muslims from the United States over security concerns in December, Ryan responded that such a move is “not who we are as a party” and in violation of the Constitution.

Trump became the presumptive Republican nominee after his two remaining rivals, Ted Cruz and John Kasich, both suspended their campaigns on Tuesday and Wednesday after they lost the Indiana primary to Trump.
