"A USMC Sargent spends 7 months in a Mexican prison for a minor charge. He is beaten. After he is returned to America, The man from Queens sends him a check for $25,000, 'To get you started.'"

This anecdote relates to the story of U.S. Marine Sgt. Andrew Tahmooressi, who was arrested in Mexico in March 2014 and spent seven months in prison there on weapons-trafficking charges after he crossed the border at San Ysidro, California. His car was found to contain three firearms and ammunition, items he legally owned and was permitted to carry in the United States, but not in Mexico.

We examined his case and the complexities surrounding it in a previous fact check. Tahmooressi's protracted detention in Mexico, along with his claims of having been beaten and restrained for weeks on end, caught the attention of several high-profile commentators in the United States, including the broadcaster and U.S. Navy veteran Montell Williams, then-Fox News anchor Greta van Susteren, and Trump.
Tahmooressi's mother Jill, who was a vocal and persistent advocate for her son's release and return to the United States, confirmed in a phone call with Snopes that Trump had indeed sent Andrew a check for $25,000 after he was released in late 2014. Trump also enclosed a letter, which Tahmooressi reproduced in her memoir. In that letter, dated Nov. 11, 2014, Trump wrote:
"It is my great honor to present you with this check for $25,000. You have served our country with fortitude and dignity, and we are fortunate to have someone like you as a brave Marine and protector of our wonderful nation. We are proud of you and I wish you and your family the very best for many years to come."

"A black bus driver saves a suicidal girl from jumping off a bridge. Our man from Queens sends him a check for $10,000."

In October 2013, Buffalo, New York, bus driver Darnell Barton made international headlines after he saved the life of a woman contemplating suicide. Barton stopped his bus and comforted the woman, who was standing on the outside of railings along an overpass, before carefully helping her on to the other side of the railings and staying with her while first responders arrived on the scene:
The Buffalo News reported at the time that Mayor Byron Brown had presented Barton with a $10,000 check from Trump in a ceremony at city hall:

How many “millions of dollars”? People around Trump have answered that question in a number of ways. A couple of weeks ago, Mike Pence, Trump’s running mate, said that anyone “who knows about Donald Trump and his career knows that this is a man who’s given away tens of millions of dollars to charitable causes throughout his business life.” In July, Trump’s son Eric said his father had given away “millions and millions and millions of dollars.” Last year, on the same day that Trump officially launched his Presidential bid, his campaign provided a specific number: a “summary of net worth” document made public that day stated that Trump had given away $102 million between 2009 and 2014.

"It is my great honor to present you with this check for $25,000. You have served our country with fortitude and dignity, and we are fortunate to have someone like you as a brave Marine and protector of our wonderful nation. We are proud of you and I wish you and your family the very best for many years to come."
