Incumbent, 80, beats back challenge from Seth Moulton, who argued Markey was too old to be effective at his job

Senator Ed Markey won the Democratic primary in Massachusetts on Tuesday, beating back a challenge from Seth Moulton, a congressman who tried to unseat him by arguing to voters his opponent was too old to be effective at his job.

Massachusetts is heavily Democratic, making the senator favored to win a third full term in the November general election, where he faces the Republican nominee, John Deaton.

Government talks up pact but Venezuelan opposition alarmed that democracy yet to return after Maduro exit

Trump administration officials on Tuesday defended a highly contentious deal giving the US control of a significant chunk of Venezuelan oil reserves, arguing that the sweeping agreement would help stabilize and rebuild democracy in the shattered South American country while giving Washington vital access to strategic crude reserves.

Last week, Donald Trump announced a “groundbreaking” deal that would give the US “majority” control over 65bn barrels – roughly one-fifth – of Venezuela’s oil reserves.

Sudden departure of Daniel Driscoll comes after Pentagon chief removed senior officers and blocked promotions, prompting warnings of a leadership crisis

A senior Senate Democrat accused Pentagon secretary Pete Hegseth of having “hollowed out” the army’s senior ranks after its top civilian leader resigned after months of internal clashes with Hegseth.

No official reason was given for army secretary Daniel Driscoll’s departure after 18 months on the job, while thousands of US soldiers are deployed in the Middle East. In a statement on Monday night, White House spokesperson Anna Kelly said Driscoll had been “highly effective in advancing President Trump’s agenda”, citing his work on “readiness and lethality” and his role in Russia-Ukraine negotiations.

Continuing resolution to approve government spending until 11 December passes 370-48 and will now go to Trump

The US House of Representatives on Tuesday approved legislation to prevent a government shutdown through the midterms, as both parties opted to defuse a volatile dispute ahead of the November elections that will decide the balance of power in Congress for the final two years of Donald Trump’s presidency.

A continuing resolution (CR) authorizing government spending until 11 December passed the House by a 370-48 vote, with only 19 Republicans and 29 Democrats in opposition. Had it not passed, lawmakers would have had until the end of September to approve new funding or face a government shutdown.

US senator says that project, a key part of Trump’s voting restrictions, is ‘perilously rushed and potentially unlawful’

A new system to screen millions of mail-in ballots for this November’s US midterm elections was thrown together so hastily, and tested so little, that a single scanning glitch could see entire batches of ballots turned away, a whistleblower has told Congress.

The project – a key part of Donald Trump’s new restrictions on voting – is “perilously rushed and potentially unlawful”, according to the US senator Richard Blumenthal, who disclosed the warning in a letter to David Steiner, the postmaster general, on Tuesday.

Markey, looking to clinch another Senate term, leads younger rival Seth Moulton in blue state’s primary poll

Democrats have spent the summer ousting long-serving incumbents in primaries across the country. On Tuesday, Massachusetts voters will decide whether that generational revolt extends to the 80-year-old Ed Markey, whose younger Democratic rival has argued that the incumbent is simply too old to serve another term.

But the Senate primary in this heavily Democratic state flips a central dynamic of previous contests, where youthful progressive insurgents have targeted – and in several cases, toppled – older incumbents they derided as avatars of an outmoded cautious establishment.
