Venezuelan opposition leader Juan Guaidó declared himself the country's interim president during a massive opposition rally in Caracas Wednesday as tens of thousands of Venezuelans took to the streets to protest the government of President Nicolas Maduro.

Driving the news: The move led President Trump to announce that he had officially recognized Guaido as Venezuela's interim leader.

The U.S. Supreme Court ruled late Wednesday that restrictions imposed on New York places of worship by Gov. Andrew Cuomo (D) during the coronavirus pandemic violated the First Amendment.

Why it matters: The decision in a 5-4 vote heralds one of the first significant actions by the new President Trump-appointed conservative Justice Amy Coney Barrett, who cast the deciding vote in favor of the Catholic Church and Orthodox Jewish synagogues.

The acting administrator of the United States Agency for International Development informed senior staff Wednesday he has tested positive for coronavirus, two sources familiar with the call tell Axios.

Why it matters: John Barsa, who staffers say rarely wears a mask in their office, is the latest in a series of senior administration officials to contract the virus. His positive diagnosis comes amid broader turmoil at the agency following the election.

COVID-19 shows a bright future for vaccines

Promising results from COVID-19 vaccine trials offer hope not just that the pandemic could be ended sooner than expected, but that medicine itself may have a powerful new weapon.

Why it matters: Vaccines are, in the words of one expert, "the single most life-saving innovation ever," but progress had slowed in recent years. New gene-based technology that sped the arrival of the COVID vaccine will boost the overall field, and could even extend to mass killers like cancer.
