On the Republican side, politicians are reasonably up in arms about this, but they seem to ignore that when „their guy“ was in the Oval Office, they were very much in favor of having the DOJ sift through reporters‘ emails. On the Democratic side, you have groups like Media Matters, ridiculously destroying its own credibility by coming out with talking points about how the DOJ did the right thing in spying on reporters. Basically, it‘s all about „defend your guy / attack the other guy“ no matter what the situation is. This obviously isn‘t true across the board — there certainly have been some party members „crossing lines“ to express horror at this kind of surveillance.
