 -- WHAT YOU NEED TO KNOW TODAY

President Trump hunkers down at Camp David today with his National Security Council, Vice President Mike Pence and Defense Secretary James Mattis to discuss strategy in Afghanistan.

After about four hours at Camp David, Trump travels back to Bedminster, New Jersey, tonight.

After Charlottesville, three Democratic House members want to censure the president and plan to introduce a formal resolution of censure today.

Barcelona held a moment of silence this morning for two terrorist attacks in Spain Thursday that left 14 dead and more than 100 injured. Trump responded Thursday by condemning the attack in Barcelona but also spreading a debunked story about World War I-era Gen. John Pershing.

THE TAKE with ABC News' MaryAlice Parks

Left alone and shunned this week, President Trump has taken to screaming and lobbing insults at folks from his Twitter account as they turn their backs and head for the door. Isolated, he has retreated to extreme nativist and racially charged language. He began Thursday, verbally spitting on two Republican lawmakers, an astounding move considering that, despite their rebuke of his recent comments, party members remain some of the only potential allies he has left. Hours later, Trump doubled-down on his defense for Confederate statues, echoing phrases used by white nationalists over the weekend about the country's "culture" being under attack. He ended the day tweeting a discredited legend about a World War I-era U.S. general's killing Muslims with bullets dipped in pig's blood. The timing appeared to be in reference to the attack in Barcelona, begging the question: Was the president of the United States suggesting that tactic? This week has arguably been the worst in his presidency and has left members of his party unsure how to pick up the pieces. The often soft-spoken chairman of the Senate Foreign Relations Committee, Bob Corker, R-Tenn., even questioned Trump's fitness for the job, telling reporters, "The president has not yet been able to demonstrate the stability nor some of the competence that he needs to demonstrate in order to be successful."

QUOTE OF THE DAY

"If they choose to take those statues down, fine ... Maybe it's appropriate to have them in museums or to put them in some sort of historical context in that regard." -- Robert Lee, great-great grandson of Gen. Robert E. Lee [CNN]

In a tweet seemingly responding to the terror attack in Barcelona, President Donald Trump referenced a factually inaccurate anecdote about combating Muslim enemies that he often repeated on the campaign trail.
