(CNN) Jimmy Kimmel is aware that there is an "expectation" that he and other late-night hosts will address tragic events like the two mass shootings in Texas and Ohio, and while he wishes they "didn't have to," he sees it as necessity.

"It's horrible," Kimmel told reporters on Monday of the tragedies. "Nobody's doing anything about it at all and we seem to forget about these tragedies nationally four days after they happen."

In recent years, Kimmel has not shied away from tackling subjects like health care, immigration and gun safety legislation on his late-night show, "Jimmy Kimmel Live!"

"My hope, always, in situations like that, is...I know I don't have any thoughts that are new or groundbreaking and usually by the time we get on the air there's been 24 to 48 hours of news coverage, but to just remind people that 97% of Americans believe that we should have background checks for purchases at gun shows and our politicians don't seem to care what we think anymore," he said.

Kimmel credited David Letterman and "The Daily Show" host Jon Stewart for being leaders in how to tackle more difficult subjects.
