The big picture: The earthquake is associated with a series of quakes that began in December, Governor Wanda Vázquez Garced tweeted, citing the Puerto Rico Seismic Network.

  • Earthquakes on the island killed at least one person, caused widespread power outages and displaced nearly 2,000 people.

Where it stands: The island is under lockdown with a strict curfew until the week of May 25 in response to the novel coronavirus. No casualties were immediately reported from Saturday's quake, the New York Times reports, citing the USGS.

Brazil coronavirus death toll tops 100,000 and case numbers surpass 3 million

Brazilian President Jair Bolsonaro posted a photo of himself to Facebook congratulating his soccer team, Palmeiras, for winning the state title Saturday, moments after the health ministry confirmed the national COVID-19 death toll had surpassed 100,000.

Why it matters: Brazil is only the second country to confirm more than 100,000 deaths from the coronavirus. On Sunday morning, it became the second country to surpass 3 million cases, per Johns Hopkins. Only the U.S. has reported more. Bolsonaro has yet to address the milestones. He has previously tested positive for COVID-19 three times, but he's downplayed the impact of the virus, which has crippled Brazil's economy.

Why it matters: Trump could face legal challenges on his ability to act without congressional approval, where the constitutional power lies on federal spending. Sen. Ben Sasse (R-Neb.) was the most vocal Republican critic, saying in a statement: "The pen-and-phone theory of executive lawmaking is unconstitutional slop."
