Attorney General Merrick Garland appeared before the Senate Judiciary Committee today, facing questions about special counsel probes, the controversial memo on anti-Catholicism, and FACE Act prosecutions.

Republicans on the committee sought to challenge Garland on his record, citing his involvement in the memo while working at the Department of Justice in the 1990s. Garland defended himself, saying he was not the author of the memo, and that he was only responsible for signing off on it.

Garland also faced questions about his plans to tackle prosecutions under the FACE Act, which protects Americans from acts of bias-motivated violence. He said he would take a “zero-tolerance” approach to such acts, and that he would work to ensure that the law is enforced.

The hearing also addressed the ongoing investigations into the Trump administration, which Garland said he could not comment on due to the ongoing nature of the probes.

Garland’s appearance on the Hill comes at a time of heightened tensions between Congress and the executive branch, as well as increased scrutiny of the Department of Justice.
