Biden: "I am the Democratic Party right now"

Responding to President Trump's insistence that the Democratic Party "wants to go socialist medicine," Joe Biden said at the presidential debate on Tuesday: "I am the Democratic Party."

Why it matters: Trump has repeatedly claimed that the Democratic nominee is not in control of his party and that he will be "dominated" by progressives like Sen. Bernie Sanders and Rep. Alexandria Ocasio-Cortez. Unlike other candidates who Biden ran against in the Democratic primary, he does not support Medicare for All or abolishing private health insurance.

Biden hits back at Trump interruptions: "Will you shut up, man?"

The first presidential debate got off to a raucous start on Tuesday night, with President Trump repeatedly interrupting Joe Biden to the point that the Democratic nominee told his opponent to "shut up."

Why it matters: About half an hour in, the debate had become increasingly difficult to watch due to the near-constant cross-talk. Some aides had feared that Biden would lose his cool in response to Trump's antics, but the result has mostly been that the debate has centered around each candidate sniping at each other, rather than putting forward a vision for the country.
