After a day of royal pomp and pageantry, President Donald Trump and British Prime Minister Keir Starmer signed a new U.K.-U.S. technology agreement that the British government hopes will help show that the allies’ trans-Atlantic bond remains strong despite other differences.

The Trans-Atlantic tech partnership signing capped a flurry of announcements on U.K. investments during Trump’s visit, which together amounted to a high-profile show of support for the country’s tech industry.

No U.S. president, or any other world leader, has ever had the honor of a second U.K. state visit.

Here’s what to know:

Trump being in Windsor doesn’t stop protests: Thousands of demonstrators marched through central London on Wednesday. Some held banners that said “No to the racism, no to Trump.” Though the protests were smaller than during Trump’s visit in June 2019, they included mini versions of a giant Trump baby blimp. In Windsor, protesters projected an image of Trump and Jeffrey Epstein on a tower at the castle.Jimmy Kimmel’s show suspended indefinitely after FCC threat: After the late-night host said “the MAGA gang” was trying to “score political points” after Kirk’s assassination and suggested Kirk’s alleged killer may have been pro-Trump, FCC Chairman Brendan Carr said his agency has a strong case for holding Kimmel, ABC and Disney accountable for spreading misinformation about the assassination. Some ABC affiliate stations said they would stop airing the show, before the network pulled the show off the air.Trump designates antifa as terrorist organization: Antifa, short for “anti-fascists,” is an umbrella term for far-left-leaning militant groups and is not a singular entity. They consist of groups that resist fascists and neo-Nazis, especially at demonstrations. It’s unclear how the administration would label what is effectively a decentralized movement as a terrorist organization.
