The Defense Department and the Energy Department's National Nuclear Security Administration in May argued in a previously undisclosed memo to Congress that the United States needs a new, more powerful nuclear warhead program because of risks and vulnerabilities in the current one, Roll Call reports.

The argument is "groundbreaking," per Roll Call, because the government rarely, if ever, acknowledges the arsenal's weaknesses. Among the issues the departments address in the "closely held" document are what they consider to be an over-reliance on one type of submarine-launched warhead that apparently isn't destructive enough and could suffer from technical problems, as well concerns about land-based intercontinental ballistic missiles that are set in a "launch under attack posture." That means the weapons are ready to launch within minutes of a reported enemy attack, which increases the risk of firing in the wake of a false alarm. And when ICBMS are launched, they cannot be returned to their silos. The Pentagon usually downplays the possibility of reacting to a false report, Roll Call reports, but the memo uses it to justify a new weapon that supposedly wouldn't carry the same risks.

Critics think developing the new sub-launched weapon, known as a W93, is unnecessary (they believe the current warheads are plenty forceful), too expensive, and could harm global non-proliferation efforts. It remains to be seen if the Pentagon and the NNSA will be able to convince Congress and whoever wins the 2020 presidential election with their arguments, but the debate will likely gain more attention going forward.

Minnesota's last four governors seem determined to make a stand for the state's "Minnesota nice" ethos, while also refuting baseless fears of vote fraud. Gov. Tim Walz (D) came up with the idea to invite his three predecessors — Mark Dayton (D), Tim Pawlenty (R), and Jesse Ventura (I) — to make and ad with him last Friday, they filmed it Monday, and Walz's office released it Wednesday, the Minneapolis Star Tribune reports. The governors agree that this is "the most important election of our lifetime" and urge Minnesotans to show patience, "civility, and decency" throughout the process.

"I asked some friends to help me explain why Election Day might be a little different this year," Walz tweeted. "The four of us don't agree on everything. But we do agree on this: The 2020 election is too important to sit out. Go vote."

Along with President Trump's frequent, false assertions about rampant mail-in vote fraud and calls for his followers to "watch" people vote, Minnesota had to swat down a plan by a Tennessee-based company to send private armed guards to "protect" the polls, the Star Tribune reports.

"Our state is proud to have one of the safest and most secure election systems in the whole country," Pawlenty said. "With so many of us voting by mail, it may take a little longer to verify a winner," Walz added. "And that's okay, it's by design," Pawlenty continued. "A delay just means out system is working," Ventura said, "and that we're counting every ballot."

In a time of deep and sometimes violent polarization, this is pretty nice, Minnesota. Peter Weber

During a press conference last week, Director of National Intelligence John Ratcliffe strayed from his approved remarks when he claimed Iran was sending emails to American voters as a way to "damage President Trump," two senior administration officials with knowledge of the matter told Politico.

This allegation was not in his prepared statement, which was shown to and signed off by FBI Director Christopher Wray and Chris Krebs, director of the Department of Homeland Security's Cybersecurity and Infrastructure Agency, Politico reports. The press conference was held so the officials could explain to voters ways foreign actors were trying to influence the U.S. election.

Democrats in several states reported receiving emails that claimed to be from the far-right Proud Boys group, threatening them and saying if they didn't vote for Trump, "we will come after you." Ratcliffe said those emails were sent by Iran, and then asserted that they were "designed to intimidate voters, incite social unrest, and damage President Trump." The officials told Politico that while the Proud Boys were named several times in his prepared remarks, Ratcliffe omitted those references.

Ratcliffe made the decision to hold the briefing on his own, officials told Politico, and it was quickly put together and timed so it would not air on television at the same time as a Trump rally. Before becoming DNI, Ratcliffe was one of Trump's most vocal supporters.

When asked for comment, Amanda Schoch, the assistant DNI for strategic communications, told Politico that "literally no one is disputing the 100 percent factual accuracy of the DNI's remarks. The rest of this is just pointless process noise, most of which is inaccurate or taken out of context." Catherine Garcia

The Supreme Court on Wednesday night let stand a lower court ruling allowing North Carolina to extend its deadline for accepting mail-in ballots.

With the extension, ballots that are postmarked by Election Day can arrive up to nine days later and still be counted. Justice Amy Coney Barrett, who joined the Supreme Court on Tuesday, did not participate in the 5-3 decision. A spokesperson said she sat this one out "because of the need for a prompt resolution and because she has not had time to fully review the parties' filings."

In June, North Carolina's state legislature moved the mail ballot deadline from Nov. 3 to Nov. 6, but the North Carolina Board of Elections extended it even further, to Nov. 12, saying this protected "lawful North Carolina voters from having their votes thrown out because of mail delays that the Postal Service had explicitly warned the state about." Under state law, the board has the authority to make temporary changes to election rules during an emergency, like the coronavirus pandemic, NBC News reports.

North Carolina's Republican Party and President Trump's campaign challenged the extension, saying it posed "an immediate threat to the integrity of the federal elections process," but a federal district court judge and the Fourth Circuit Court of Appeals both refused to block the change.

North Carolina Attorney General Josh Stein (D) said it was "a disgrace that Republicans are trying to block eligible voters from having their votes counted. If voters comply with the statute and mail in their ballots on or before Election Day, they should not be penalized by slow mail delivery in a pandemic." Catherine Garcia

The president of the FBI Agents Association sent letters to both President Trump and Democratic presidential nominee Joe Biden on Wednesday, asking that the winner of next week's election keep FBI Director Christopher Wray in his position.

Earlier this week, people close to the president told Axios that if Trump is re-elected, he plans on immediately firing Wray; he reportedly became enraged in September when Wray testified there is no evidence of widespread voter fraud, contradicting Trump's claims.

The FBI Agents Association represents more than 14,000 agents, and its president, Brian O'Hare, wrote in his letters that since 1976, FBI directors have had 10-year terms, which keeps the position nonpartisan. While the president is able to remove FBI directors, "doing so could lead to instability and damage to the Bureau's operations," O'Hare said.

Wray has been leading the FBI since August 2017, after Trump fired its former director, James Comey, that May, as he investigated Russian meddling in the 2016 election. O'Hare said in his letters that Wray is "an asset to the Bureau and a trusted leader of agents in the field" and "the country is safer because of him." He has "not led the Bureau in a political manner," O'Hare added, "and politics should not determine his fate as director."

The Biden campaign did not immediately respond to The Washington Post's request for comment, and White House spokesman Judd Deere said in an email, "If the president doesn't have confidence in someone he will let you know. The White House does not speculate or comment on personnel matters." Catherine Garcia

The Supreme Court on Wednesday refused to expedite a request from Pennsylvania Republicans to stop the state from counting mail-in ballots received in the three days after Election Day.

This means the case won't be heard before Nov. 3, but in a statement, Justices Samuel Alito, Clarence Thomas, and Neil Gorsuch said it could be reviewed by the court after the election.

Earlier this month, the Supreme Court deadlocked on the issue, leaving in place the Pennsylvania Supreme Court's ruling that ballots postmarked by Election Day can be counted if they arrive up to three days later. Wednesday's brief order did not say why the Supreme Court declined to expedite consideration of this similar case, The New York Times reports.

Justice Amy Coney Barrett, whose first day on the job was Tuesday, did not cast a vote on Wednesday, with a spokesperson for the court saying she "did not participate in the consideration of this motion because of the need for a prompt resolution of it and because she has not had time to fully review the parties' filings."

Hurricane Zeta made landfall near Cocodrie, Louisiana, on Wednesday evening as a Category 2 storm with winds of 110 mph, the National Hurricane Center said.

Cocodrie is on the state's southeastern coast, about 65 miles south-southwest of New Orleans. Zeta is a fast moving storm, going north-northeast at almost 25 mph, CNN reports. It is the fifth named storm to hit Louisiana this season.

Forecasters say Zeta will likely move inland, passing over or near New Orleans, and residents are being urged to stay inside. Zeta crossed Mexico's Yucatan Peninsula on Tuesday, where its heavy winds brought down trees and power lines. Catherine Garcia
