A federal judge heard arguments Wednesday on a lawsuit alleging the Trump administration hasn’t properly prevented aides from using encrypted apps such as Signal that delete messages after they're read, Politico reports. Watchdog group Citizens for Responsibility & Ethics in Washington (CREW) and the National Security Archive filed the lawsuit last year.

Why it matters: Last February the White House told aides that they must save official messages they send or receive on social media platforms, which the DOJ lawyer said amounts to a ban on encrypted apps. Trump’s Department of Justice wanted to have the case thrown out.

  • The DOJ lawyer argued that two cases from the D.C. Circuit Court of Appeals in the 1990s provide precedent to keep the courts from reviewing the president’s record management in the first place.
  • If that ends up being the case, that could effectively give the White House broad leeway to ignore obligations of Presidential Records Act, a lawyer from CREW argued.
  • The federal judge didn’t indicate whether he intends throw out the case.

Brazil on Saturday began distributing the 2 million doses of the AstraZeneca coronavirus vaccine that arrived from India Friday, Reuters reports.

Why it matters: Brazil has the third highest COVID-19 case-count in the world, according to Johns Hopkins University data. The 2 million doses "only scratch the surface of the shortfall," Brazilian public health experts told the AP.

U.S. national security adviser Jake Sullivan spoke on the phone Saturday with his Israeli counterpart Meir Ben Shabbat, Israeli officials tell Axios.

Why it matters: This is the first contact between the Biden White House and Israeli prime minister's office. During the transition, the Biden team refrained from speaking to foreign governments.

President Biden told his Mexican counterpart, Andrés Manuel López Obrador, on a phone call Friday that he plans to reverse former President Trump’s “draconian immigration policies.”

The big picture: The Biden administration has already started repealing several of Trump’s immigration policies, including ordering a 100-day freeze on deporting many unauthorized immigrants, halting work on the southern border wall, and reversing plans to exclude undocumented people from being included in the 2020 census.
