The Equal Employment Opportunity Commission (EEOC), a federal agency tasked with enforcing civil rights laws in the workplace, has opened a probe into complaints from Lester Wilson and Mario Torres, who were forced to fight their way out of Hamilton Hall nearly a year ago, The Post has confirmed.

“We welcome the EEOC’s decision to open an investigation into Mario’s and Lester’s charges of discrimination,” former US Attorney General Bill Barr, whose firm Torridon is representing the two men, told The Post.

“Columbia has a legal and moral obligation to protect the civil rights of its students and employees. It must be held accountable when it fails to do so,” Barr, 74, who attended Columbia University and lived through the riots of the late 1960s there, added.

It is not fully clear when the EEOC commenced the probe, but records seen by The Post show that the agency was working on the investigation last month.

Wilson and Torres, who had worked at the school for over five years, were both left injured as well as traumatized from the scourge of anti-Israel unrest that engulfed the Ivy League school and have since been unable to return to work as a result, according to the complaints they filed last October.

“Hours after President [Minouche] Shafik issued her statement [that the university had become ‘unsafe for everyone‘], an antisemitic mob assaulted two janitors inside Columbia’s historic Hamilton Hall, calling them ‘Jew-lovers,’” the two complaints for both men recalled of the Hamilton Hall takeover in April last year.

“Columbia had indeed become unsafe for everyone, including the two janitors who were trapped inside Hamilton Hall. And for these two men, Columbia had for months been a hostile environment in violation of Title VII,” the complaints added.

Both men are making claims under Title VII of the Civil Rights Act, alleging that they faced retaliatory harassment at the institution for “reporting antisemitic and racist conduct.”

It all began around November 2023, shortly after the bloody Oct. 7 Hamas attack on Israel sparked a war. Racist and antisemitic graffiti started to pop up, scrawled all around Hamilton Hall — and the campus’s janitors were forced to clean it up.

“Mr. Wilson recognized the swastikas as symbols of white supremacy,” Wilson’s complaint alleges. “As an African-American man, he found the images deeply distressing. He reported them to his supervisors, who instructed him to erase the graffiti.”

“No matter how many times Mr. Wilson removed the swastikas, individuals kept replacing them with more.”

Wilson lost track of how many swastikas he had to scrub, but his colleague Torres, who is Latino, pegged it in the dozens and eventually reached a point where he had enough, his complaint said.

“They were so offensive, and Columbia’s inaction was so frustrating, that he eventually began throwing away chalk that had been left in the classrooms so vandals would not have anything to write with,” Torres’ complaint alleged.

“However, Mr. Torres was reprimanded by his supervisor for doing so.”

Given the fact that Columbia University requires an electronic ID to gain entrance to Hamilton Hall, which is nestled on the school’s Morningside Heights campus, and the fact that the building was equipped with security feeds, the two janitors felt the authorities could’ve tracked down the perpetrators.

They had reported the deluge of antisemitic, sexually obscene and racist graffiti at Hamilton Hall to campus security and concluded there was “no reason to believe” Columbia University “investigated any of the incidents” that had been flagged.

In one instance, around Dec. 6, 2023, Torres and Wilson observed masked protesters storm through Hamilton Hall chanting “From the river to the sea, Palestine will be free” and scrawling swastikas as well as other obscene graffiti in the building.

After Wilson reported that, he was told by campus security that “the trespassers and vandals were exercising their First Amendment rights” and that “nothing could be done,” per the complaint.

The antisemitic incidents on campus continued to occur.

Eventually, anti-Israel protesters erected encampments in a nod to the wretched conditions that scores of Palestinians endured in Gaza during the war.
