Joe Biden's campaign was reportedly hit by suspected Russian state-backed hackers after they unsuccessfully tried to breach SKDKnickerbocker, a Washington-based strategy and communications firm that has been working with the campaign.
The US Treasury also sanctioned Ukrainian lawmaker Andrii Derkach for election interference against Mr Biden, including promoting “false and unsubstantiated” allegations.
It came as Democratic vice presidential candidate, Kamala Harris, visited Florida in an effort to drum up more support from voters in the battleground state.

All the rage in the Beltway, meanwhile, was "Rage" itself, Bob Woodward's upcoming book. Biden said Donald Trump had 'no conception' of national security after revelations the president boasted about classified nuclear weapons systems to veteran journalist Bob Woodward.
Biden, meanwhile, will have a chance to face Trump more directly, with his campaign announcing the pair would hold competing events in Minnesota next Friday.
