Republican presidential candidate Donald Trump put a call out on Twitter Monday for questions via a hashtag. The result, in addition to the trending #AskTrump -- on a day that Threshold Editions announced a forthcoming Trump book would be released Oct. 27 -- was a slew of negative questions.

He began answering the questions around 1 p.m. EST with a series of short videos. He did not respond to the (many) derisive questions, though he did tackle a couple on the sillier side.

For instance, to @MarketMavensInc's NFL query, "If Tony Romo is out for the season, what chance do the Cowboys have of a playoff," Trump said that the quarterback's injury was "a terrible thing for the Dallas Coyboys," though he finds the team's defense to be "excellent."

And for those unsure of Trump's connected circle, he included that Romo is "a great guy. I know him."

Answering "how would you fix the student debt crisis?" (from @EliseChristine), Trump spoke in generalities,  saying, "we are going to restructure it ... so it's very affordable," but did not offer specifics.

He also approached a question about homlessness in the U.S. (from @mdmrestoration) vaguely, acknowleding it is a "big problem" that largely comes down to a loss of jobs to other countries. "We're taking our jobs back," he said, without elaborating.

He tackled a couple of more polarizing issues, including gun control and Israel.

For the former, he stated, "I am very pro second amendment," referring to "just released papers" on the subject at donaldjtrump.com. He then repeated that he's "very. pro. second. amendment."

As for "How will you protect Israel?" (@dixie hilton), Trump said that the country had been "let down badly by the Obama administration" and that, "I will totally protect Israel."
