Human rights activist Kristine Lucius said on Monday that Democrats will rise up in the fight over President Trump Donald John TrumpBiden on Trump's refusal to commit to peaceful transfer of power: 'What country are we in?'

Lucius suggested that though Democrats face an uphill fight in defeating any Trump pick given the GOP's Senate majority, it is not impossible.

“I think if you look at just what happened a year ago, a lot of people would have said Democrats couldn’t have stopped the repeal of ObamaCare," Lucius, who serves as the executive vice president and director of policy at the Leadership Conference on Civil and Human Rights, told Hill.TV's Krystal Ball and Buck Sexton on "Rising."

"But what happened was people rose up. The people demanded the Senate not take away their health care. I think you’re going to see the same exact thing here in the Supreme Court fight because that’s exactly what’s on the line again," she continued.

“This president has told us what kind of justices he wants to put on the court, and right at the heart of that is access to health care," she added. “If you look at what happened a year ago, I think everyone was counting out the Democrats, and the progressive left on health care a year ago, but instead we stopped the repeal.”

Lucius, who is a former Democratic Senate Judiciary Committee staffer, was referring to Senate Republicans' failed attempt to make good on their longtime campaign promise to repeal and replace the health-care law.

The GOP effort to repeal the law has since faded from the party's priority list due to the party's narrow 51-29 Senate majority.

Lucius's comments come as Trump plans to unveil his pick to replace outgoing Justice Anthony Kennedy on the nation's highest court on July 9.

The vacancy has given the president the opportunity to fill the seat with a more conservative justice.

Trump said last week he has narrowed down his list to five people.
