U.S. Sen. Chuck Schumer is questioning why the FBI didn't re-interview the older brother suspected in the Boston Marathon bombing when he returned from Russia and posted "inflammatory" comments on the Internet.
Schumer tells The Associated Press he's a big supporter of the FBI, which has foiled numerous terrorism attempts. But he says something went wrong this time.
Schumer says Monday he'll pursue an answer as a member of the Senate Judiciary Committee. The committee oversees the FBI.
He says the FBI should have talked again with 26-year-old Tamerlan Tsarnaev (TAM'-ehr-lun tsahr-NEYE'-ehv) when he returned from a six-month stay in Russia and then posted the remarks.
Tsarnaev died in a gun fight.
His younger brother, Dzhokhar Tsarnaev (joh-HAHR' tsahr-NEYE'-ehv), is in custody.
There was no initial comment from the FBI.
