BOSTON (AP) — U.S. Rep. William Keating says a congressional committee's investigation into the Boston Marathon bombings has reinforced that the biggest threat to the U.S. is the radicalization of homegrown terrorists.
The Massachusetts Democrat spoke by phone Monday from Moscow, where he and House Homeland Security Committee Chairman U.S. Rep. Michael McCaul, R-Texas, are looking into the marathon bombings and reviewing security procedures in Sochi ahead of the Olympics.
Keating says the committee is close to finishing its report on the April 15 bombings near the marathon finish line that killed three people and injured more than 260 others. It should be released early in February.
He says it appears dead bombing suspect Tamerlan Tsarnaev met with insurgents in Russia but didn't pass their vetting process and instead returned to the U.S.
