Wealthy progressive activist Tom Steyer is not satisfied with House Speaker Nancy Pelosi’s declaration that Donald Trump is “not worth” impeachment.

Steyer has been advocating, and building a case for, Trump’s impeachment and removal from office for some time.

Despite many House Democrats also supporting impeachment, Pelosi has long resisted pushing that option as it would be divisive and the Senate likely lacks Republican support to actually remove Trump from office.

The California Democrat seemed to close the door on impeachment with her comment that Trump isn’t “worth it.”

Steyer, who has pursued Trump’s impeachment with commercials, town hall meetings across the country, as well as TV appearances, wants Pelosi to pursue impeachment even if it’s politically difficult.

“What we have here is constitutional oversight task that is directly given to Congress to make sure to protect our system itself and to delegate that to the Justice Department and the criminal justice system after he has been president, means that in fact they decided not to uphold the Constitution, they decided to overlook the rule of law, and they decided to put the American people and our safety at risk,” Steyer said during a recent segment on MSNBC.

“In fact, when people say there is one way to get rid of him or another, actually you are making a decision,” Steyer added. “Nancy says in her statement in The Washington Post, we know he’s unfit for office. We know he has broken the law. All of those things we’ve decided in Washington, D.C. that in fact we are not going to do anything about it because it’s politically difficult. So unless Republicans give us permission to do something, we are going to sit on our hands and let him go unaccountable.”

Public hearings–such as the recent session held with former Trump fixer Michael Cohen before the House Oversight and Government Reform Committee–will convince the American public that Trump needs to be removed, Steyer said.

Some 54 percent of those polled do not want Trump impeached, opposed to 42 percent who do, according to a Monmouth poll released earlier this month.

“Well, I believe that this president is the biggest crisis for America in a generation,” Steyer said. “And I believe that when people get a chance through hearings like the hearing with Mr. Cohen in front of the House Oversight Committee, Americans will be glued to their TV sets that they will in fact see with their own eyes directly how lawless this president is, and they will insist that he be removed from office. But they have to have public hearings to be able to see it on TV and make up their own minds.”
