Uber is ending its self-driving car testing in Arizona and will focus on resuming operations in Pittsburgh sometime this summer, it said on Wednesday.

Yes, but: The company remains barred from testing its cars in Arizona after one of its self-driving cars struck and killed a pedestrian in Tempe in March. Through the ongoing investigation of incident, it says it determined it's safer to test in the cities where it also has engineering outposts.

The story has been updated to clarify that Uber is focused on resuming testing this summer only in Pittsburgh, not San Francisco.

Several cities are ending curfews after the protests over the death of George Floyd and other police-related killings of black people led to fewer arrests and less violence Wednesday night.

The latest: Los Angeles and Washington D.C. are the latest to end nightly curfews. Seattle Mayor Jenny Durkan tweeted Wednesday night that "peaceful protests can continue without a curfew, while San Francisco Mayor London Breed tweeted that the city's curfew would end at 5 a.m. Thursday.

Sen. Lisa Murkowski (R-Alaska) said Thursday that she agreed with former Defense Secretary James Mattis' criticism of President Trump, calling it "true and honest and necessary and overdue."

Why it matters: Murkowski, who has signaled her discomfort with the president in the past, also said that she's "struggling" with her support for him in November — a rare full-on rebuke of Trump from a Senate Republican.

Facebook said Thursday it will begin blocking state-controlled media outlets from buying advertising in the U.S. this summer. It's also rolling out a new set of labels to provide users with transparency around ads and posts from state-controlled outlets. Outlets that feel wrongly labeled can appeal the process.

Why it matters: Nathaniel Gleicher, Facebook's head of security policy, says the company hasn't seen many examples yet of foreign governments using advertising to promote manipulative content to U.S. users, but that the platform is taking this action out of an abundance of caution ahead of the 2020 election.
