Famed lawyer Alan Dershowitz called on Deputy Attorney General Rod Rosenstein not to “bully” Congress after reports came out that said Rosenstein had threatened House Intelligence Committee lawmakers and aides with a subpoena.

“The legislature has the power, obviously, to oversee and investigate the executive branch. And a member of the executive branch, which is what Rod Rosenstein is, shouldn’t be able to bully the legislative branch,” Dershowitz said during an interview on Fox News late Tuesday.
