(AP) WASHINGTON - Sen. Dianne Feinstein wants to know what the FBI learned when it interviewed Boston Marathon bombing suspect Tamerlan Tsarnaev (tsahr-NEYE’-ehv) after his six-month stay last year in the Russian provinces of Dagestan and Chechnya.
The FBI had been tipped off a year earlier by Russian officials that 26-year-old Tsarnaev, who was killed last week in a shootout with police, was worth investigating for possible extremist ties.
Feinstein, chairwoman of the Senate intelligence committee, wants senior FBI officials to testify as soon as Tuesday to explain what they learned and why they did not pursue the matter further.
The surviving suspect, 19-year-old Dzhokhar Tsarnaev, remains hospitalized and was charged Monday.
