New Jersey Sen. Cory Booker on Sunday said he and members of the Democratic Party should hold back from talking about impeaching President Trump.

"I just wanted to tell you right now, I'm not going to rush to impeachment. I think we need to deal with this in a very sober way. This can't be a relitigation of an election that's now passed. This has to be an objective assessment about the facts that are going on right now," Booker told CNN "State of the Union" guest host Dana Bash.

Booker, speaking from Poland, praised Hillary Clinton's commencement speech at Wellesley College Friday. He called her remarks "inspiring" overall and criticized those who have focused on her linking in the speech Trump to former President Richard Nixon, who resigned from office before being impeached.

"First of all, cut Secretary Clinton some slack. People might want to rush to criticize her. Listen to the whole speech. It was a very beautiful speech," Booker said.

In the Friday address, Clinton said she and her classmates were "furious" about Nixon's election in the late 1960s.

"We were furious about the past presidential election. Of a man whose presidency would eventually end in disgrace with his impeachment for obstruction of justice ... after firing the person running the investigation into him at the Department of Justice," Clinton said, not mentioning Nixon or Trump's names.

Other Democratic lawmakers, including House Minority Leader Nancy Pelosi and Senate Minority Leader Chuck Schumer, have distanced themselves from calls for Trump's impeachment. Instead, the Democratic leaders have urged the various investigations to come to a completion before Congress take any action against Trump.
