From CBS News:

Paul Rosenzweig, who served in the Department of Homeland Security under Republican President George W. Bush,¬†described the actions of federal agents in Portland as “on the borderlines of legal.”

“Never have I seen it before where the federal government has imposed its will on the state and says, ‘We’re going to do this mission whether you want us here or not,'” Rosenzweig told CBS News’ David Martin.
