Republican presidential candidate Donald Trump held a Twitter question and answer session from Twitter's New York office on Sept. 21. During the question and answer session, Trump vowed to close the United States borders as soon as he is in office.
When asked what he would do on his first day as President, Trump responded with a video message, in which he said, "The first thing I'd do in my first day as president is close up our borders so that illegal immigrants cannot come into our country."
"We have tremendous problems," he added, "we owe $19 trillion dollars, we don't know what we're doing, everything's falling apart. People can come into our country, but only legally. I will close up those borders."
The hashtag #AskTrump was used for the question and answer session, during which the wealthy real-estate mogul was asked questions on a variety of topics, including Israel, gun control, immigration, student debt and NFL players.
Trump has been dominating the Republican presidential race for some time now, yet the most recent CNN/ORC International poll -- which was released on Sept. 20 -- revealed that support for the Republican front-runner has dropped by 8 percent, The Hill reports.
Trump may have taken to Twitter in a bid to garner the same online interest and interaction that other presidential candidates, like Hillary Clinton, have sparked by using social media to field questions.
During his Twitter Q-and-A, Trump released about a dozen short videos. In the first video, Trump said that he would "totally protect Israel" if he were to be elected president.
"They've been let down badly by the Obama administration," he said. "Israel will be very secure if I win this election. Believe me, Israel will be very, very secure."
When asked what his top three priorities as president would be, Trump responded that he would "immediately solve the problems that we have with health care. Premiums are going through the roof."
"People can't afford it," he added. "It's a disaster. I'll strengthen up the border, I'll take care of our vets, and I'll rebuild the military. We will have a strong, strong nation, and one that really people are going to be in love with again."
