President Trump will meet with major GOP donors for a private dinner on Tuesday in New York as part of a fundraising effort for the Republican National Committee, according to three people briefed on his plans.

The dinner is to convene as the polls close in Alabama, where Sen. Luther Strange (R), a Trump ally, is fending off a conservative challenger in a high-stakes GOP primary runoff in a special Senate election.

The evening gathering is set to be held at Le Cirque, a French restaurant in Manhattan.

Many of the Republicans' most prominent financiers have been invited, the three people said, speaking on the condition of anonymity because they were not authorized to discuss the matter publicly.

One of them said they expect Trump to talk to donors — some of whom have groused recently about stalled proposals on taxes and health care — about the party’s agenda on Capitol Hill and his outlook on next year’s midterm elections.

A White House official and a spokesman for the RNC declined to comment.
