Mr. Meadows didn’t just act as a doormat to President Trump; he seemed to let everyone have his or her way. Even as he tried to help Mr. Trump remain in office, Mr. Meadows agreed to give a deputy chief of staff, Chris Liddell, the go-ahead to carry out a stealth transition of power to Joe Biden. This made no sense, but it was just the way Mr. Meadows rolled. Mr. Trump’s chief is a world-class glad-hander and charmer.

As part of the efforts to subvert the 2020 election, Mr. Meadows paraded a cast of incompetent bootlickers into the Oval Office. This culminated in a wild meeting on the night of Dec. 18, 2020 — when Mr. Trump apparently considered ordering the U.S. military to seize state voting machines before backing down. (Even his servile sidekick Rudy Giuliani objected.) A few days later, Mr. Meadows traveled to Cobb County, Ga., where he tried to talk his way into an election audit meeting he had no right to attend, only to be barred at the door.

All the while, the indictment shows that Mr. Meadows was sharing lighthearted remarks about claims of widespread voter fraud. In an exchange of texts, Mr. Meadows told the White House lawyer Eric Herschmann that his son had been unable to find more than “12 obituaries and 6 other possibles” (dead Biden voters). Referring to Mr. Giuliani, Mr. Herschmann replied sarcastically: “That sounds more like it. Maybe he can help Rudy find the other 10k?” Mr. Meadows responded: “LOL.”

Mr. Meadows’s testimony this week that his actions were just part of his duties as White House chief of staff is a total misrepresentation of the position. In fact, an empowered chief can reel in a president when he’s headed toward the cliff — even a powerful, charismatic president like Ronald Reagan. One day in 1983, James A. Baker III, Mr. Reagan’s quintessential chief, got word that the president, enraged by a damaging leak, had ordered everyone who’d attended a national security meeting to undergo a lie-detector test. Mr. Baker barged into the Oval Office. “Mr. President,” he said, “this would be a terrible thing in my view for your administration. You can’t strap up to a polygraph the vice president of the United States. He was elected. He’s a constitutional officer.” Mr. Reagan’s secretary of state, George Shultz, who was dining with the president, chimed in, saying he’d take a polygraph but would then resign. Mr. Reagan rescinded the order that same day.

Why did Mr. Meadows squander his career, his reputation and possibly his liberty by casting his lot with Mr. Trump? He once seemed an unlikely casualty of Mr. Trump’s wrecking ball — he was a savvy politician who knew his way around the corridors of power. In fairness to Mr. Meadows, three of his predecessors also failed as Mr. Trump’s chief. “Anyone who goes into the orbit of the former president is virtually doomed,” said Jack Watson, Jimmy Carter’s former chief of staff. “Because saying no to Trump is like spitting into a raging headwind. It was not just Mission Impossible; it was Mission Self-Destruction. I don’t know why he chose to do it.”
