President Donald Trump blasted the International Association of Fire Fighters on Wednesday for its endorsement of Joe Biden for president.
His attack came in an early morning tweet.
The president wrote:
"I've done more for Firefighters than this dues sucking union will ever do, and I get paid ZERO!"
To back up his point, Trump retweeted posts from about 60 former or current firefighters and their families in support of him.
Trump had also taken aim at the union Monday after Biden had secured the endorsement from the IAFF.
In a Monday tweet, he said the "firefighters' leadership will always support Democrats, even though the membership wants me."
