Washington DC – This Black History Month, members of the Squad are speaking out on a series of bomb threats targeting historically Black colleges and universities (HBCUs).

At least 16 HBCUs were forced to shut down on Tuesday – the first day of Black History Month – due to bomb threats, the Washington Post reported.

The day before, at least six HBCUs received similar threats. Just one month prior, on January 4, eight institutions were on the alarm.

The schools targeted on Tuesday spanned different states, including Mississippi, Georgia, Maryland, Missouri, Kentucky, Louisiana, Arkansas, Florida, and the District of Columbia.

On Wednesday, members of the Squad condemned the threats as the latest outbreak of supremacist violence in the country's long history of racial oppression.

Massachusetts Rep. Ayanna Pressley tweeted, "During slavery, Black folks were lynched for learning to read. During Jim Crow, we fought for equality in education & still do today. This week, our #HBCU students were threatened with bombs. To a hate-fueled few, there is nothing more dangerous than an educated Black person."

Missouri Rep. Cori Bush, a graduate of Harris-Stowe State University, one of the institutions targeted, said in a statement, "Black History Month is meant to be a celebration of the rich, powerful, and beautiful legacy of Black Americans. Yet today, on the first day of that celebration, historically Black colleges and universities across the country – including in St. Louis – are instead met with the violent backlash of white supremacy."

"To anyone who thinks these kinds of threats will stop Black excellence, hear me say this: we are unstoppable," she continued.

Law enforcement officers say they have not found any actual bombs in their investigations, but the incidents have left a feeling of deep unease on campus.
