The two are trying to find common ground after Mr Ryan said he could not endorse the presumptive Republican nominee.
He has said the businessman lacked conservative principles.
"We had a great conversation this morning," the two wrote in a joint statement.
"While we were honest about our few differences, we recognise that there are also many important areas of common ground."
They said they would be having "additional discussions" but think they can unify the party and win the election.
At a press conference following the meeting, Mr Ryan said he was "very encouraged" by what he heard from Mr Trump.

What a load of chit. If the Republicans don't win this election they are out of cards moving forward. They have played all of their jokers/wildcards and have nothing left.
