House Speaker Paul Ryan and presumptive GOP presidential nominee Donald Trump will speak by phone Wednesday night, both Trump's campaign and Ryan's office confirmed.

The call follows a news conference earlier Wednesday during which the Wisconsin Republican tamped down rumors that he is preparing to formally endorse Trump for the presidency.

"I don't have a timeline in my mind, and I have not made a decision," Ryan told reporters. "Nothing has changed from that perspective and we're still having productive conversations."

Ryan is preparing to roll out six GOP policy blueprints in June on issues such as poverty reduction, replacing Obamacare and reining in the power of the presidency. Ryan said these are not proposals that Congress can pass while President Obama is still in office, so the agenda is intended to create a road map for Congress once a Republican president is sworn in.

To that end, Ryan said his staff has been discussing the policy ideas with Trump's campaign. "I think it is important that we actually discuss the principles that we all share in common and the policies that come from them ... that is the kind of conversations we are having."

Ryan said discussions with Trump are ongoing. "Our staff talk virtually every day," the speaker said. "We are having good conversations ... that's all what you need to do to begin to get on the same page."

The phone call was first reported by Bloomberg.
