Senate Majority Leader Mitch McConnell is warning Democrats to think carefully about “presidential harassment” if they win the majority of the House.

The Kentucky Republican told The Associated Press in an interview Wednesday that Democratic threats to investigate President Donald Trump’s finances and businesses would “help the president get re-elected” in 2020.

He recalled how Republicans were enthusiastic about going after President Bill Clinton in the 1990s. The GOP-led House impeached Clinton but the Senate acquitted him. The public was not as supportive as Republicans had hoped.

McConnell says ‘It worked exactly the opposite. The public got mad at us and felt sympathy for President Clinton.”

McConnell added that “this business of presidential harassment may or may not quite be the winner they think it is.”
