(CNN) Rep. Chris Collins acknowledged that he has no evidence to support President Donald Trump's claim that 3 to 5 million people voted illegally in the election, but refrained from contradicting the President and said he would support an investigation.

"That's his opinion," Collins, R-New York, told CNN's Chris Cuomo on "New Day" Wednesday. "There are illegal votes cast and if we can tighten down, we should do it."

His comments came shortly after the President tweeted that he will be asking for a major investigation into voter fraud in the 2016 election. Trump has repeatedly claimed that illegal votes cost him the popular vote, but has not provided any evidence to support his statement.
