Speaker Paul Ryan (R-Wis.) is warning donors that the Republican party's House majority could be in jeopardy, according to The New York Times.

Ryan spoke in private last week to a group of donors at a political conference in Colorado sponsored by the industrialists Charles G. and David H. Koch.
During the conference, the speaker said donors shouldn't put their focus completely on retaining the Senate, and noted that Republican control of the House may also be at risk, the Times reported, citing a Republican who heard the talk.

There is reportedly growing concern among the party's biggest contributors over retaining control of Congress with Donald Trump as the party's nominee.

Democrats would need to pick up more than 30 House seats to take control. But according to the Times, Republicans are worried about a scenario in which they lose enough seats that Ryan is weakened and the party is on the defensive.

The Times report on Saturday painted a broad picture of Republicans worried about the impact of Trump on down-ballot races.
