Former House Speaker Newt Gingrich offered advice to President Donald Trump, who is facing a divided Congress as President Clinton did after Gingrich's GOP took power in the 1994 "Republican Revolution."

"The right thing to do is to congratulate [Rep. Nancy Pelosi (D-Calif.) and] work on substance [including] infrastructure reform and investment," he said.

Gingrich said that Trump must lead on two fronts -- working with Democrats to approve meaningful legislation, while litigiously battling Democratic committees bringing legal challenges against him.

Reps. Jerrold Nadler (D-N.Y.), Maxine Waters (D-Calif.), Elijah Cummings (D-Md.) and Peter de Fazio (D-Ore.) are likely to challenge the White House as presumptive committee chairmen, according to Fox News' Laura Ingraham.

Gingrich said he agreed with Senate Majority Leader Mitch McConnell (R-Ky.), who warned Democrats against pursuing drastic measures like impeachment.

Gingrich said his Republican caucus was able to work well with Clinton on issues -- but that the relationship "degenerated" when the GOP pursued impeachment against the Arkansas Democrat for lying about a sexual encounter with Monica Lewinsky.

He said that Trump should "focus on being president, rather than being the leader of the opposition party to Nancy Pelosi."
