Nancy Pelosi issues a surprising warning for Trump's State of the Union speech

House Minority Leader Nancy Pelosi (D-Calif.) issued a surprising warning for those attending President Donald Trump's State of the Union speech Tuesday — but it was to Democrats, not Republicans.

Here's what she said:

Fox News' Chad Pergram reported that Pelosi delivered a "stern warning" to Democrats that were to attend the speech. "Play nice," his tweet said.

He added that Pelosi didn't want a repeat of the outburst during former President Barack Obama's address to Congress where a Republican yelled "you lie!" after he claimed Obamacare would never provide health care for illegal immigrants.

Pergram also said that Pelosi told Democrats to not attend the speech if they were planning to walk out in protest. She is quoted as saying they should allow Trump to be his "slobbering self."

“If you want to walk out, don’t come in," she said, according to a report in Politico.

Pelosi reportedly told Democrats at the meeting that there were such lowered expectations for Trump that he could do nearly anything and call it a success.

“If his nose isn’t running and he isn’t burping, he did a great speech,” she reportedly remarked.

Several Democrats said they will boycott the speech, while Supreme Court Justice Ruth Bader Ginsberg will also skip the speech in favor of a previously planned speech she is scheduled to give.
