President Donald Trump's campaign accused Democratic presidential candidate Michael Bloomberg of being "clearly racist" over his past support of the NYPD's use of "stop and frisk."

In 2015 audio that resurfaced this week, Bloomberg can be heard defending the policy, which he would eventually go on to disavow before running for president.

Trump responded by calling Bloomberg a "total racist" on Twitter.

“WOW, BLOOMBERG IS A TOTAL RACIST!” Trump reportedly wrote.

Trump's campaign also issued a statement calling Bloomberg a racist.

Throughout the years, Trump has been on record in support of expanding the stop and frisk policy to other cities.

In a statement, Bloomberg argued that Trump's anger was a sign of fear.
