President Donald Trump‘s pick to oversee the U.S. Attorney’s Office for the District of Columbia, Ed Martin, is an “egregiously unqualified political hack who has never served either as a prosecutor or judge,” according to former prosecutors — 103 of them to be exact — who voiced their opposition this week to Martin’s nomination in a letter.

The former assistant U.S. attorneys have reportedly teamed up to call for a rare Senate Judiciary Committee hearing where Martin can be questioned on statements he’s made about the 2020 election being stolen from Trump and his firings of people who investigated the Jan. 6 Capitol attack earlier this year after being appointed to the post of interim U.S. Attorney for the District of Columbia by the president.

The group of former prosecutors banded together Monday, the same day that Sen. Adam Schiff, D-Calif. — a member of the Judiciary Committee — announced he would be placing a hold on Martin’s nomination, citing his “troubling conduct in his months as Interim U.S. Attorney in the same role.”

While Martin is currently awaiting his Senate confirmation, it is rare for nominees to be subjected to Senate Judiciary Committee hearings before a vote, according to The New York Times, which obtained a copy of the letter from the former prosecutors Monday, along with local NBC affiliate WRC.

“Martin’s flagrant misconduct is a danger to law enforcement, the rule of law, and the United States Constitution itself,” the letter said. “It would be an insult to the rule of law to deny the honorable law enforcement professionals who were unjustifiably thrown under the bus for doing their duty such an opportunity,” the group added, in reference to fired Jan. 6 investigators. “Martin is an egregiously unqualified political hack who has never served either as a prosecutor or judge and who has no meaningful roots in the District of Columbia or even the surrounding area.”
