"The Donald" is getting a visit from yet another GOP hopeful Monday. Newt Gingrich is scheduled to stop by Trump Tower Monday morning to meet with the business mogul.

"As to the sum and substance of the conversation to take place, there is no set agenda," said Trump aide Michael Cohen. "I suspect, like the other Republican candidates, Newt will seek Mr. Trump's advice and endorsement."

Characterizing it as a "meeting with an old friend," Gingrich's campaign told Fox News their candidate would, of course, welcome an endorsement from Donald Trump.

Trump and Gingrich have spoken infrequently by phone over the course of the campaign season and this will be their first scheduled meeting, making the former House Speaker the fifth candidate to officially pay the business mogul a visit.

Mitt Romney, Rick Perry, Herman Cain, and Michele Bachmann have all sought to court an endorsement from the real estate developer and reality television show star.
