Former Vice President Joe Biden told CNN's Chris Cuomo in an interview on Tuesday that President Trump is "a joke."

Why it matters: He was responding to Sarah Sanders' remarks at her press briefing on Tuesday that Trump was "joking" when he called Democrats treasonous for their glum reactions during his State of the Union. Biden also told Cuomo he'd tell Trump not to talk to special counsel Robert Mueller if he were one of the president's lawyers: "The President has some difficulty with precision."

Cardiologists are increasingly concerned that coronavirus infections could cause heart complications that lead to sudden cardiac death in athletes.

Why it matters: Even if just a tiny percentage of COVID-19 cases lead to major cardiac conditions, the sheer scope of the pandemic raises the risk for those who regularly conduct the toughest physical activity — including amateurs who might be less aware of the danger.

President Trump cast an outdated vision of "the 'suburban housewife'" as he swiped this week at Joe Biden's newly minted running mate Kamala Harris — building on his months-long play to drive a wedge through battleground-state suburbs by reframing white voters' expectations.

The big picture: As he struggles to find an attack that will stick against the Biden campaign, Trump for a while now has been stoking fears of lawless cities and an end to what he's called the “Suburban Lifestyle Dream.” It’s a playbook from the ‘70s and ‘80s — but the suburbs have changed a lot since then.

Trump tightens screws on ByteDance to sell Tiktok

President Trump added more pressure Friday night on China-based TikTok parent ByteDance to exit the U.S., ordering it to divest all assets related to the U.S. operation of TikTok within 90 days.

Between the lines: The order means ByteDance must be wholly disentangled from TikTok in the U.S. by November. Trump had previously ordered TikTok banned if ByteDance hadn't struck a deal within 45 days. The new order likely means ByteDance has just another 45 days after that to fully close the deal, one White House source told Axios.
