DETROIT, Mich. — The biggest lesson Joe Biden learned from the first debate is that there are no rules of engagement at these things, and he's ready to throw down at tonight's debate, according to five senior campaign officials.

What to watch: Yes, he's going to keep contrasting himself with President Trump. But he's squarely focused on Sen. Kamala Harris, too, after the first debate in Miami.

  • "We’re not joking when we say he’s not going to let his record be mischaracterized," said one senior campaign official. "It’s not OK to label someone as a racist."
  • They were referring to Harris' line to Biden at the last debate that started with: "I know you're not racist, but ... "
  • "Some folks are willing to go places we didn’t think they’d go,” said another senior Biden campaign official, who said they were surprised by Harris' exchange with him because she's been friends with Biden for years.
  • His team maintains he won't make any personal attacks against other Democrats, but Biden himself has said he won't be as "polite" as last time.

Why it matters: Any time Biden has to spend defending his record from other candidates' attacks is less time he'll have to take on Trump — something he's been doing since he launched his campaign, signaling he views himself as the eventual nominee.

Between the lines: Although Harris saw a bump in polling after her spat with Biden, his team believes that was temporary.

  • "This is not a new dynamic," said one senior Biden campaign official. "You see candidates who rise and the balloon pops once there’s more information on that person."
  • After the Miami debates, Harris reached 20% in a Quinnipiac poll, but she's since leveled back out at around 11%.

Health care dominated last night's discussion, which Biden watched, and he plans to present that as one of the major differences between himself and Harris, as well as Sen. Bernie Sanders.

The bottom line: Biden might be ready for a fight, but Harris is surely not the only one to go after him and his record, and that could introduce new vulnerabilities he's not yet anticipating.

Go deeper: Democrats prepare for debate brawl with Biden.

A series of powerful "atmospheric river" storms are delivering historic amounts of rainfall across parts of drought-stricken California and the Pacific Northwest — triggering widespread power outages and flooding.

Why it matters: The strong atmospheric river, packing large amounts of moisture, is causing Northern California to whiplash from drought to flood.

Saudi dissident claims MBS said he could get "poison ring" to kill king

A former senior Saudi intelligence official who worked with the U.S. on counterterrorism alleged to "60 Minutes" in an interview broadcast Sunday that Crown Prince Mohammed bin Salman discussed in 2014 killing the kingdom's then-monarch.

Why it matters: The claim by the exiled Saad al-Jabri, whom Saudi authorities describe as "a discredited former government official," that the crown prince, known as "MBS," allegedly said he could obtain a "ring from Russia" to carry out the attack, is one of several serious but unproven allegations he made on the CBS show.

“You blew it”: GOP activist turns on corporations over vaccine mandates

The chairman of the American Conservative Union said on "Axios on HBO" he accepts "Joe Biden is my president, and I want him to succeed," but predicted Republicans retake the House and Senate in 2022 — with greater than 50% odds Donald Trump runs in 2024.

The big picture: In a joint interview with his wife, Mercedes, Matt Schlapp also refused to share their vaccination status. And he told corporate America "you blew it" by embracing vaccine mandates and liberal social stances that have alienated GOP voters and politicians.
