The TV news covered the court with wall-to-wall coverage.

It becomes a familiar script.

Two months after the arraignment of former President Donald J. Trump in a Manhattan courtroom was extensively covered in a separate case, the national television news media was back in action Tuesday afternoon in Miami.

Three of the major broadcast networks – ABC, NBC and CBS – interrupted their usual afternoon programming to cover the news. NBC sent its evening news anchor, Lester Holt, to Miami, as did CBS with Norah O’Donnell.

The cable news networks turned to the top news anchors. Jake Tapper and Anderson Cooper oversaw coverage on CNN, and Bret Baier and Martha MacCallum assisted coverage on Fox News.

Like Mr. Trump’s journey to a Manhattan courthouse, the six major broadcast and cable news networks all used aerial photos to show Mr. Trump’s motorcade making the roughly 20-minute journey to downtown Miami, where the former president was sued.

The room-to-wall coverage represented another day when Mr. Trump dominated the airwaves. Many of the panelists participating in the coverage discussed the momentous nature of the day.

“Whenever politics and law collide, there’s always tension because they’re both places of fighting,” CBS’ John Dickerson said from an impromptu set on a balcony overlooking the Miami courthouse. “Politics is fighting in the pub, and the law is more like a boxing match – there are some rules.”

Unlike the arraignment in April, there was a definite lack of usable footage. There were no photos of Mr. Trump entering the courthouse – his motorcade entered a garage – nor were there any images in the federal building. The networks instead relied on footage of protesters outside the courthouse.

Fox News aired live footage of a person described by the network’s anchors as Melania Trump, the former first lady — though within minutes the network said it wasn’t, in fact, her. “On a day like this, with so much coming and going, it’s easy to confuse two people from a distance,” said John Roberts, the Fox host, who clarified that it was actually Margo Martin, a Trump aide.

Earlier in the day, Fox News held a press conference outside the Miami courthouse by Vivek Ramaswamy, a Republican presidential candidate, asking other candidates to pardon Mr. Trump. Five hours later, Mr. Ramaswamy sat down for a live Fox News interview with Ms. MacCallum, this time in the New York studio. “You’re moving fast today,” she noted, before denouncing a “politicized charge.”

Throughout the day, MSNBC seemed to look ahead, displaying an image in the lower-right corner of the screen, featuring an image of Rachel Maddow, Nicolle Wallace, and Joy Reid, announcing a prime-time “post-arraignment special” at 8 p.m. .”

The news about Mr. Trump has been good for MSNBC ratings. Last week, the network tied for No. 1 among cable news networks in total primetime viewers for the entire calendar week — the first time it had achieved that in more than two years. The network averaged 1.52 million viewers, narrowly beating Fox News’s 1.51 million viewers and CNN’s jaw-dropping average of 677,000 viewers.

It was also MSNBC’s highest viewership during weekday primetime hours since Mr. Trump’s indictment in April.
