Sen. Amy Klobuchar, D-Minn., believes President Trump's off-the-cuff tweets are ruining the opportunities the president and Congress have to pass legislation.

"The president has to govern," Klobuchar said on "Fox News Sunday." "And not just squander those moments away when he sends out tweets at seven in the morning. I do think there are many of us that want to govern, that believe we are in a crisis in the economy. We are at a time of opportunity, so let's use that opportunity."

Klobuchar doubled down on that sentiment when Fox News host Chris Wallace asked her whether the president is trying to get rid of Deputy Attorney General Rod Rosenstein and special counsel Robert Mueller.

"I hope not," Klobuchar said. "These tweets, really every time one goes out it does squander this moment of governorship."

Klobuchar said Democrats could come together with Republicans and the White House on infrastructure, workforce training and tax reform.

"But it's going to be really hard to do that when those tweets come out at seven in the morning and then the whole focus of Washington and the country in on what the president said last time. Let's use this moment to govern."

Trump has been accused of undermining his administration's messaging with his early-morning tweets reacting to the FBI's investigation into Russian meddling and attacking his critics on the social media platform.
