President Trump threatened to close the U.S.-Mexico border — or "large sections" of it —by next week unless Mexico "immediately" stops "all illegal immigration" in a series of Friday tweets.

"This would be so easy for Mexico to do, but they just take our money and 'talk.' Besides, we lose so much money with them, especially when you add in drug trafficking etc.), that the Border closing would be a good thing!"

The big picture: While Trump has made a similar threat on Twitter before, he hasn't attached a timeline in the past. It's not clear exactly how he'd follow through on his threat, though the Washington Post reported last year that he planned to deny asylum to migrants at the border using proposed emergency powers similar to the 2017 travel ban.

NIAID director Anthony Fauci told CNN on Friday evening that if "people are not wearing masks, then maybe we should be mandating it."

Why it matters: Fauci made the comments the same day the U.S. hit its highest daily COVID-19 case count since the pandemic began.

Harris to Black voters: Casting a ballot is about honoring your ancestors

Sen. Kamala Harris appealed to Black voters in Georgia on Friday, urging them to "honor the ancestors" by casting ballots, and again calling President Trump a "racist."

Why it matters: The U.S. saw a significant decline in African-American voter turnout between 2012 and 2016, reaching its lowest point since 2000. Higher turnout among Black Americans this year could tip the balance in favor of Democrats in key battleground states, including Georgia.
