But Trump was criticizing Sessions for doing something that endorses Trump's own belief that his campaign was unfairly targeted by the Justice Department and the FBI.
Trump tweet: Why is A.G. Jeff Sessions asking the Inspector General to investigate potentially massive FISA abuse. Will take forever, has no prosecutorial power and already late with reports on Comey etc. Isn't the I.G. an Obama guy? Why not use Justice Department lawyers? DISGRACEFUL!
The tweet refers to a request by federal authorities to the Foreign Intelligence Surveillance Court in 2016 to wiretap former Trump campaign advisor Carter Page, who was suspected of having contacts with Russians.
Trump expressed irritation that Sessions has asked the Justice Department's internal watchdog, the Office of the Inspector General, to probe whether prosecutors abused their powers in targeting Page. The inspector general, Michael Horowitz, was appointed in 2012 by then-President Barack Obama.
