Trump sets Twitter ablaze after firefighters union backs Biden

Trump's response comes two days after the country's largest union of firefighters endorsed Biden, the former vice president who shot to the top of opinion polls after entering the race last week.Trump began his tirade at dawn by quoting Fox Newspersonality Dan Bongino, who said he knew no firefighters who would vote for Biden."I've done more for Firefighters than this dues sucking union will ever do, and I get paid ZERO!" Trump wrote on Twitter, without elaborating.
