"[N]ot enough nuclear experts may exist to visit the hundreds of buildings, track down the voluminous records and conduct the comprehensive inspections required to verify compliance" with a North Korean denuclearization deal, the L.A. Times' David Cloud reports.

The issue: "U.S. intelligence agencies believe Pyongyang has assembled as many as 60 nuclear weapons and built a widely dispersed network of secret development and production facilities, some deep underground in the country’s rugged northern mountains."

  • "[I]f Kim ... agrees to disarm in stages over the next decade or longer, the most likely outcome if a nuclear deal ultimately is struck, the massive effort would require hundreds of international nuclear inspectors to help dismantle warheads, shut down facilities, interview North Korean scientists, unravel procurement systems, physically tag and monitor bomb-making equipment."
  • Why it matters: "Nothing approaching such a sweeping agreement with a closed police state like North Korea has been attempted in the history of nuclear disarmament."

Joe Biden's campaign released his 2019 tax returns on Tuesday, showing that he and his wife, Jill, paid nearly $300,000 in federal taxes last year.

Why it matters: The release, timed just hours before the first presidential debate, comes days after a bombshell New York Times report said that President Trump paid only $750 in federal taxes in 2016 and 2017. Biden's team is hoping to make the tax contrast a sticking point during their showdown.

New York City's coronavirus positivity rate has ticked up to 3.25%, its highest since June, Mayor Bill de Blasio said at a news conference on Tuesday.

Why it matters: The jump — from 1.93% on Monday — came on the first day that public elementary classrooms reopened in the city after months of closures, but guidelines state that all public schools will have to shut if the citywide seven-day positivity rate stays above 3%.
