Washington | The US Postal Service has sent warnings to 46 states that it may not be able to deliver their ballots on time for the November election, as Democrats, including House Speaker Nancy Pelosi, blasted the Trump-appointed postmaster general.

Former president Barack Obama escalated the Democratic response to the mail slow-down on Friday (Saturday AEST), accusing President Donald Trump of trying to "actively kneecap the Postal Service" to suppress the vote. The nation's mayors said safe voting, including vote-by-mail "must be a national priority".
