The FDNY comes under fire for hiring a recruit, who had previously been in trouble for racist tweets.

A protest was held Monday outside the department's headquarters in Downtown Brooklyn.

Those in attendance say Joseph Cassano, the son of former commissioner Salvatore Cassano, is a bigot and not fit to serve.

He resigned from his post as an EMT back in 2013 for issuing racist and anti-semetic tweets.

Now, Cassano is set to join the FDNY Academy next Monday.

"He can't be trusted," said Kirsten John Foy, of the National Action Network, which organized the protest. "What if he goes into a burning building and has to make a decision between his life and the life of an African American or the life of a Jewish person?

"That's an unacceptable situation to have a victim put in, and we can't rely on the words of others to sanitize this man's own words."

The FDNY issued a statement saying:

"EMT Cassano has passed all requirements for promotion to Firefighter and is scheduled to enter the upcoming probationary Firefighter class."
