Vermont Sen. Bernie Sanders won the Democratic caucuses in Utah and Idaho Tuesday night, but earlier in the day the presidential candidate stopped by ABC's "Jimmy Kimmel Live" to share his thoughts on a very busy news cycle.

In an interview with host and comedian Kimmel, Sanders discussed many topics, not the least of them the deadly terror attack in Brussels Tuesday morning. Kimmel asked Sanders why Americans seem to gravitate toward the toughest-talking candidate, in this case Republican front-runner Donald Trump, in the aftermath of a terrorist attack.

"I think people get afraid, and for good reasons. ISIS is a disgusting, barbaric organization. We’ve seen what they’ve done in Paris, what they’ve done in Brussels. People are afraid of an attack in the United States. But I think what we have to understand is we’re not going to undermine the Constitution of the United States of America in order to effectively destroy ISIS," Sanders responded. "At the end of the day, we cannot allow the Trumps of the world to use these incidents to attack all of the Muslim people in the world. That is unfair. That is not what this country is about."

That same day, Trump told Fox News that “we have to be very, very vigilant as to who we allow into this country," adding that as president he would "close up our borders to people until we figure out what is going on."

Trump's poll numbers surged after the bloody November 2015 terrorist attacks in Paris. ISIS has claimed responsibility for both the attacks in Paris and in Brussels.

Later in the interview, Kimmel asked Sanders about his relationship with Hillary Clinton, specifically if Sanders thought his campaign had contributed to the Democratic front-runner's historic unfavorability numbers.

Sanders denied the claim, adding, "I think what I have had tried to do in this campaign is to focus on the real issues impacting the American people, and that is something that is sometimes hard to do in the media because the media is not necessarily interested. We have been very careful about not attacking Secretary Clinton in any kind of personal way. Other people do that. We do not."

Despite his wins in Utah and Idaho Tuesday, Sanders is still trailing Clinton in the delegate count. Clinton, who won Arizona Tuesday, has 1,214 pledged delegates, while Sanders lags behind with 911. Sanders has been closing the gap as of late, but the senator may not have enough time left to make up the deficit and win the nomination, especially when Clinton's large superdelegate lead is taken into account. The Democratic candidates next face each other Saturday in primaries in Alaska, Hawaii and Washington.
