But congressional testimony on Wednesday by the inspector general, Michael Horowitz, underscored the report’s bleak portrayal of the F.B.I. and its wiretapping powers in ways that extend well beyond the Russia investigation.

News analysis: “At more than 400 pages, the study amounted to the most searching look ever at the government’s secretive system for carrying out national-security surveillance on American soil,” our Washington correspondent writes. “And what the report showed was not pretty.”

N.J. attacker wrote anti-Semitic posts

One of the two assailants in the deadly attack in Jersey City that ended at a kosher supermarket had published anti-Semitic posts online and was a follower of a fringe religious group that has expressed hostility to Jews, officials said on Wednesday.

The attackers, who were among the six people killed, were identified as David Anderson and his girlfriend, Francine Graham. The pair are also suspected of killing a livery driver in nearby Bayonne, N.J., whose body was found on Saturday.
