Former Attorney General Bill Barr said on Saturday that former President Donald Trump would need to surround himself with a certain set of people if he wins next year’s election and reclaims the White House. According to Barr, the GOP front runner’s second term will be made considerably better by people that can tell him “no.”

Speaking to Fox News, Barr said Trump “needs people around him who will push back and help keep him on the straight and narrow.”

“During his first term, the main way that could be done is by pointing out to him how this would hurt his prospects for a second term. Once he wins a second term, I don’t know — you know — what considerations can be used to push back against bad ideas,” he added.

For a successful second term, the next U.S. attorney general must be able to push back against Trump’s wishes if they do not align with the Constitution.

“He has to be ready to say ‘no’ and to resign. Trump has made it plain that he’s going to respond to what he considers the left wings’ ‘no holds barred’ approach by fighting fire with fire. I think for people going into that administration. I think they have to be ready to oppose the abuse of government power,” he stated.

Barr also voiced concerns that Trump’s aim for reelection might not be about the country’s interests but about retribution.

“I’m worried that his style of governance, his continuing to pander to anger and frustration versus a constructive approach to solving our problems, is going to be chaotic and not accomplish very much. He’ll be a lame duck president,” he stated.

Barr’s interview comes days after he condemned the Colorado Supreme Court’s ruling that Trump should be kept off the state’s presidential primary ballot in 2024.

While he emphasized his opposition to Trump’s candidacy, he said, “I think this kind of action of stretching the law, taking these hyper-aggressive positions to try to knock Trump out of the race are counterproductive. They backfire. As you know, he feeds on grievance, just like a fire feeds on oxygen. This is going to end up as a grievance that helps him.”
