Sunday on ABC’s “This Week,” 2020 Democratic presidential hopeful former Rep. Beto O’Rourke (D-TX) accused President Donald Trump of committing crimes and said if he wins the presidency, he will direct his Justice Department to prosecute Trump.

Partial transcript as follows:

STEPHANOPOULOS: We heard House Speaker Nancy Pelosi say this week, she wants to see the president in prison. Do you think the president committed crimes that could be prosecuted?

O’ROURKE: He did. I think that’s clear from what we have learned from the Mueller report. But I think those crimes might extend beyond what we have seen in the Mueller report; using public office for personal gain, for himself and for his family, the relationship that he has with Vladimir Putin, which has never been properly explained from the invitation as a candidate to have Russia involve itself in our election, his efforts to obstruct justice, the fact that he called Vladimir Putin after the Mueller report was released, called it a hoax, thereby giving him a green light to further participate in our democracy and our elections. If with don’t hold the president accountable we’ll set the precedent that some people in this country, because of their position of power, are in fact above the law. And if we do that, we’ll lose this democracy forever. Regardless of the popularity of the idea or what the polling shows us, we must proceed with impeachment so we get the facts and the truth and at end of the day there’s justice for what was done to our democracy in 2016.

STEPHANOPOULOS: Even if the House impeaches, the Senate isn’t going to convict the president. If you win in 2020, would you the Justice Department to pursue charges against President Trump?

O’ROURKE: I would want my Justice Department, any future administration’s Justice Department to follow the facts and the truth and to make sure at the end of the day there’s accountability and justice, without this, without that, this idea, this experiment of American democracy comes to a close. We were attacked unlike any other time in our 243-year history and we have a president who yet to acknowledge it and a president who has yet to be brought to justice. Yes, no matter who that is.
