MSNBC’s Joe Scarborough on Monday accused President Donald Trump‘s 2020 re-election campaign donors of “funding white supremacy.”

“This president never tones down his rhetoric,” said Scarborough. “In fact, for those of you who are funding Donald Trump’s re-election campaign, you may want to take note that because you keep writing checks to this president, it’s on you, it really is. You are funding this white supremacist campaign.”

The comments from Scarborough, a former Republican congressman from Florida, follow a shooting at a Walmart in the predominantly Hispanic city of El Paso, Texas on Saturday that killed 21 people. The gunman was found to have posted a manifesto linked to white supremacist views online just minutes before the massacre.

Patrick Crusiusthe perpetrator of the El Paso attack, voiced his hatred of what he viewed as a Latino “invasion” of Texas. Many Democratic politicians were quick to blast Trump for his rhetoric that has emboldened white supremacists multiple times since he took office.

Trump’s 2020 campaign and the Republican National Committee raised a combined $108 million in the second quarter of 2019.

The hashtag #WhiteSupremacistinChief quickly began trending on Twitter in the wake of the shooting.
