By Jamie Ross and Hannah Jewell  Email Listen to this briefing Good morning. It’s Thursday, July 18, and we’re obsessed with this potty-mouthed parrot who started threatening volunteers at a New York animal shelter. Now let’s get to the news. Sen. J.D. Vance headlined the Republican National Convention last night. What to know: Donald Trump’s running mate introduced himself, and his wife and family, to the nation. He focused on his upbringing in Ohio. We fact-checked him here. Today: Trump will give his speech in Milwaukee. His voters have largely brushed off his court cases, and some at the RNC have adopted his ear bandage. Follow live updates here.

He canceled events and will isolate in Delaware while continuing to work. It’s bad timing: Biden faces a political crisis. Yesterday, Rep. Adam Schiff(Calif.) became the 23rd Democratic lawmaker to publicly urge Biden to end his re-election bid. That’s not all: Democratic leaders privately warned Biden his candidacy may damage hopes of controlling the House and the Senate.

The latest: Local police officers told the Secret Service before Saturday’s rally that they did not have resources to watch the building later used by the shooter, officials said.

How he did it: As authorities chased Marset, he would vanish — only to reappear with another soccer club, a Post investigation found. Read the first of the two-part series here.

Leading the pack: “Shogun” got 25 nods, including best drama, and “The Bear” got 23 — breaking the record for a comedy series. Jon Hamm got two acting nominations.

A gross, century-old problem: Swimming in the Seine has been banned since 1923 because of high bacteria levels. But officials want the river to be the star of the Paris Games. It’s good to go: Anne Hidalgo took a dip yesterday and declared the Seine sufficiently clean. It will be used in floating Opening Ceremonies on July 26, then for some swimming events.

(Pompeii Archaeological Park) What you’re looking at: One of two unfortunate people who probably survived the eruption of Mount Vesuvius in 79 A.D. — only to be killed by an earthquake, a new study found. How we know: The skeletons had fractures resembling those of modern-day earthquake victims. So it seems that historically bad day was even worse than previously thought. Read this story
