Two Democratic lawmakers with experience on intelligence and security committees have called for information about the latest breach to be released publicly.

The California Democratic congressman, Eric Swalwell, posted on social media that he was seeking a briefing on the breach, and that while he considered Donald Trump “the most despicable person ever to seek office” – someone who had also called for hacking in the past – “that doesn’t mean America ever tolerates foreign interference”.

Adam Schiff, the Democrat of California, urged Department of Homeland Security officials to declassify information on the foreign nature of the hack. Schiff said the US intelligence community “moved much too slow to properly identity the hacking and dumping scheme carried out by Russia” in 2016 and “should act quickly here”. He also said that in that year:

The Trump campaign welcomed Russian interference, took advantage of it and then sought to deny it, much to the detriment of the country.

The New York Times has confirmed it received the same or similar trove of Donald Trump presidential campaign documents as other media outlets did, after Microsoft confirmed that a “high-ranking official” at a presidential campaign was a hacking target.

For the third US election in a row, hacked campaign information by a foreign power is now likely to feature as potential disruption. The Trump campaign has said its email systems were breached by hackers working for Iran.

Politico reported getting emails from someone who identified themselves only as “Robert” and sent internal campaign communications and a 271-page-long research dossier on Trump’s running mate, the Ohio senator JD Vance, that was part of his vetting process. The news organisation said the Vance profile was “based on publicly available information”.

Donald Trump plans to sue the US justice department for $100m for executing a search warrant at his Mar-a-Lago estate to retrieve classified government documents, according to a report.

The former president’s lawyers intend to sue the department for its conduct during the FBI’s raid on Mar-a-Lago on 8 August 2022, amid the federal investigation into his alleged retention of classified records, Fox News reported on Monday.

Trump’s legal team will argue that the DoJ was engaged in a “clear intent to engage in political persecution” when it searched his property, the report says. It quotes Trump attorney Daniel Epstein as saying:

What President Trump is doing here is not just standing up for himself – he is standing up for all Americans who believe in the rule of law and believe that you should hold the government accountable when it wrongs you.

When Elon Musk took over as owner of Twitter, researchers and elections officials feared a rampant spread of misinformation that would lead to threats and harassment and undermine democracy.

Their fears came true – and Musk himself has emerged as one of its main drivers.

The tech billionaire has cast doubt on machines that tabulate votes and mail ballots, both common features of US elections. He has repeatedly claimed there is rampant non-citizen voting, a frequent Republican talking point in this election.

Musk, the ultra-wealthy owner of Tesla and other tech companies, is scheduled to interview Donald Trump on Monday, where they are sure to find common ground on these election conspiracy theories.

Musk is a vocal supporter of the former US president and current Republican nominee. He has restored the Twitter/X accounts of people banned under previous ownership, dismantling the platform’s fact-checking and safety features. Trump’s X account, which was suspended after the January 6 insurrection, was restored as well, though Trump has not returned actively to the platform.

Donald Trump will sit down with Elon Musk for an interview tonight, nearly a month after the tech billionaire and owner of X officially endorsed the Republican presidential candidate.

Trump will participate in the interview on X, scheduled for 8pm ET on Monday, from his Mar-a-Lago residence in Florida while Musk will be in Austin, Texas.

According to Musk, the interview will be “unscripted with no limits on subject matter, so should be highly entertaining!”

Following Musk’s takeover of X, formerly Twitter, he restored Trump’s account, which was suspended by the platform’s former owners following the 6 January 2021 attack on Congress by his supporters.

Good morning US politics readers. More Americans trust Kamala Harris with the US economy than they do Donald Trump, according to a new poll that suggests the former president losing the advantage he had over Joe Biden.

The poll, conducted by the Financial Times and the University of Michigan, found that 42% of voters trust Harris on economic issues – one percentage point ahead of Trump.

The survey “marks a sharp change in voter sentiment following President Joe Biden’s withdrawal from the White House race” last month, the Financial Times reported. While Trump’s numbers were unchanged from last month’s poll results, Harris’s standing was a seven percentage point improvement compared with Biden’s numbers in July.

But three weeks into her presidential campaign, Harris has yet to unveil her economic policy platform, and Democrats are warning the Democratic presidential candidate and her running mate, Minnesota governor Tim Walz, that they must solidify their economic message before Republicans bring it back to the forefront of the campaign. On Saturday, Harris said she would be releasing an official economic policy platform in the coming days. She told reporters:

It’ll be focused on the economy and what we need to do to bring down costs and also strengthen the economy.
