Former Acting Solicitor General Neal Katyal told MSNBC last night that he believed the president had “gotten away with so much” and described his actions as “lawless.”

The author of Impeach: The Case Against Donald Trump also told the network that he believed the courts would “bring him and his ilk to justice.”

Katyal made his remarks about President Trump in the wake of the commander-in-chief’s decision to pardon seven people yesterday— including former New York police commissioner Bernie Kerik, who was convicted of tax fraud in 2010, and the “junk bond king” Michael Milken.

The president also commuted the sentences of ex-Democratic Governor Rod Blagojevich of Illinois and three others.

Speaking on The Beat with Ari Melber last night, Katyal said: “I think this country has a robust tradition of law, and yes the president’s gotten away with so much. But I have news for him: the law is going to come after him.

“What he’s doing is lawless, it’s unprecedented, it breaks every rule in our constitutional democracy, and the law will find a way to catch up with him.”

The Obama-era Supreme Court lawyer added: “He can pardon his Mar-A-Lago friends, and pardon his campaign contributors and this or that, but one way or another, our system is robust enough between the press and the courts to bring him and his ilk to justice.”

“I really want people to understand that there is still a lot out there and a lot of work to be done,” Katyal later said. “But we shouldn’t give up.”

Newsweek has contacted the White House for comment and will update this article with any response.

Under the rules set out in Article II of the U.S. Constitution, the president has the power to “grant reprieves and pardons” for federal “offenses against the United States,” with cases of impeachment being the only exception.

In a statement released on Tuesday, the White House said President Trump chose who would benefit from Tuesday’s pardons and commutations based on “the decisions these individuals have made following their convictions to work to improve their communities and our Nation.”

The commander-in-chief’s political rival and Democratic primary frontrunner Bernie Sanders took a different view on the pardons.

In a statement posted on Twitter yesterday, the Vermont senator accused Trump of granting “clemency to tax cheats” and “corrupt government officials” with his pardon power.
