White House Press Secretary Sarah Huckabee Sanders said that Democrats "oppose everything" and "do nothing" in advance of the president's selection of the next Supreme Court justice to replace Anthony Kennedy.

"It's frankly gotten really sad that their party has no message, no leadership [and] no solutions," Sanders said Tuesday.

She said that Democrats want to fight President Trump, who is doing "amazing things" for the country.

She also implored Democrats to stop fighting Trump and the positive results his administration has yielded thus far, such as an economic boom and job growth.

"One day after the next, great things are happening ... and this president is leading that effort," Sanders said.

Democrats should support the success that the country has seen, Sanders said, "particularly because they have no ideas of their own."

President Trump has said he will announce his Supreme Court nominee to replace the retiring Kennedy next Monday.

He interviewed four potential candidates on Monday.

“They are outstanding people. They are really incredible people in so many different ways, academically and every other way, and I had a very, very interesting morning," Trump said.

Sanders said Tuesday on "Fox & Friends" that the president is looking for a nominee with "tremendous intellect" and someone who will uphold the Constitution.

Justice Kennedy's retirement will give the president the opportunity to move the court solidly to the right, and a vacancy on the court could become a key issue in the midterm elections.

Sanders also addressed Washington Post columnist Jennifer Rubin's remarks Sunday that said Sanders "has no right to live a life of no fuss, no muss."

"These people should be made uncomfortable," Rubin said on MSNBC. "I think that's a life sentence, frankly."

Sanders said that it's "sad" to see where politics in America has gotten, and that people can agree to disagree in a much more civil way.
