WASHINGTON — Revelations that the FBI committed serious errors in wiretapping a former Trump campaign aide have spurred bipartisan calls for change to the government’s surveillance powers, including from some Republicans who in the past have voted to renew or expand those powers.

Anger over the errors cited in this week’s Justice Department’s inspector general’s report of the Russia investigation has produced rare consensus from Democrats and Republicans who otherwise have had sharply different interpretations of the report’s findings. The report said the FBI was justified in investigating ties between the campaign and Russia, but criticized how the investigation was conducted.

The report cited flaws and omissions in the government’s warrant applications under the Foreign Intelligence Surveillance Act, documenting problems with a surveillance program that Democrats and civil libertarians have long maintained is opaque, intrusive and operates with minimal oversight. They now have been joined by Republicans who are irate that FBI officials withheld key information from judges when they applied to eavesdrop on former Trump aide Carter Page.

“I’m still trying to get my arms around the proposition that a whole bunch of conservative Republicans who’ve logged years blocking bipartisan FISA reforms are now somehow privacy hawks,” said Sen. Ron Wyden, D-Ore.

It’s unclear what steps, if any, Congress could or will take to rein in the FBI’s power under the surveillance law, and it remains to be seen whether outrage over the way a Trump ally was treated will extend to less overtly political investigations.
