Republican frontrunner du jour Newt Gingrich will meet with real estate mogul, reality star and onetime presidential candidate Donald Trump on Monday. Mr. Trump has declared his intent to make an endorsement in the race and has held similar meetings with Sarah Palin, Rick Perry, Mitt Romney, Herman Cain and Michele Bachmann.

Throughout the spring, Mr. Trump flirted with the possibility of a White House bid. He spent some time atop the polls before ultimately deciding not to run in May. Since then, Mr. Trump has declared his intent to endorse one of the Republican candidates. Ms. Bachmann recently floated his name as a possible running mate in the (increasingly unlikely) event she wins the nomination.

Mr. Gingrich's swing through New York will also include a Tea Party-sponsored town hall in Nicotra's Ballroom at the Hilton Garden Inn in Staten Island Saturday afternoon. Mr. Trump is set to moderate a Republican presidential debate hosted by the conservative news site Newsmax and Ion Television in Iowa December 27.
