Biden rally: Vice President Joe Biden will hold his first campaign rally for Hillary Clinton next month in his hometown of Scranton, Pa. Biden had planned to campaign for Clinton this month but postponed after five police officers were killed in Dallas. The White House said the event will be Aug. 15. Scranton has dual significance — it's also where Clinton's father lived for years.

Simon sings: Paul Simon sang "Bridge Over Troubled Water" at just the right time, it seems. Sen. Al Franken and Sarah Silverman had just finished talking about their support for Hillary Clinton and Bernie Sanders — Franken for Clinton and Silverman for Sanders. Then Silverman urged Sanders' supporters to vote for Clinton. The crowd broke into loud chants of "Bernie, Bernie."

Bloomberg to endorse: Michael Bloomberg will endorse Hillary Clinton in a prime-time speech at the convention on Wednesday. The endorsement from the former New York City mayor could resonate with swing voters and Republicans who haven't warmed up to Donald Trump.

Ask Trump: Donald Trump will take questions from the public on a web forum during the third night of the Democratic convention. The Republican presidential nominee will participate in an "Ask Me Anything" event Wednesday night on Reddit. Users can begin asking questions at 6:30 p.m. and Trump will start responding at 7 p.m.

Poll bump: The Republican convention generated a modest increase in Donald Trump's poll standing, moving him back into a lead over Hillary Clinton. Through Sunday, the USC Dornsife/Los Angeles Times "Daybreak" tracking poll of the race shows Trump gaining about 3 percentage points in the aftermath of the convention. That would be roughly in line with the convention bounces enjoyed by Democratic and Republican nominees in the last three election cycles. As of Sunday, the poll, which is updated daily, showed Trump leading Clinton 45 percent to 41 percent. The lead is within the poll's margin of error of 3 percentage points in either direction.

New face: Baltimore Mayor Stephanie Rawlings-Blake called the 47th Democratic convention to order. Her formal welcome was briefly held up by a slight oversight — she forgot the gavel and had to retrieve it offstage. Rawlings-Blake was a last-minute fill-in for Debbie Wasserman Schultz, the ousted DNC leader.
