Noel and Thomas will both be released on $100,000 bond. Lindsey Graham, a South Carolina Republican and chairman of the Senate Judiciary Committee, asked about the FBI investigation.
Epstein was put in his cell alone at 7:49 p.m. following an attorney visit and wasn't checked on between 10:30 p.m. and 6:30 a.m. the following day, when Thomas and fellow guard Tova Noel, 31, found him hanging while delivering his breakfast, the indictment says.
Both guards surrendered themselves to authorities Tuesday morning, prosecutors said.
Her comments came at the same time federal prosecutors in NY lodged criminal charges against the two guards responsible for monitoring Epstein.
Ms. Hawk-Sawyer said Epstein was only one of two suicides that happened this year at a high-level secure facility.
Epstein was awaiting trial in August for alleged sex trafficking when he reportedly hanged himself at the MCC.
This comes as the director of Federal Bureau of Prisons was pressed on Capitol Hill about the agencies suicide watch program regarding Epstein.
They were supposed to check on Epstein every half hour - but instead, they fell asleep for hours and allegedly falsified records to cover up what they had done.
Dr Michael Baden, the former chief medical examiner for New York City, said that he now suspects foul play, most likely strangulation.
Prosecutors allege that instead of making their required rounds, the two guards sat at their desks, browsed the internet and walked around the unit's common area.
The outlet reported that the two unnamed guards were arrested after reportedly failing to check on Epstein, who was placed on suicide watch in July, just weeks before reportedly taking his own life.
"As alleged, the defendants had a duty to ensure the safety and security of federal inmates in their care at the Metropolitan Correctional Center", U.S. Attorney Geoffrey S. Berman said Tuesday. And don't rush it so that they don't do a thorough investigation.
Baden, the pathologist hired by Epstein's brother to investigate his death, said he still was not convinced and wanted to know more from guards about the position of Epstein's body when he was found. To hide their failure to perform their duties, NOEL and THOMAS repeatedly signed false certifications attesting to having conducted multiple counts of inmates when, in truth and in fact, they never conducted such counts.
A spokesperson for the American Federation of Government Employees, a union representing federal correctional officers and other government workers, did not immediately respond to a request for comment.
