(Reuters) President Barack Obama pledged on Friday that the United States will find out whether the two ethnic Chechen brothers suspected of carrying out the Boston Marathon bombings received help, and he pleaded for Americans not to rush to judgment.
Obama appeared in the White House briefing room after police arrested the lone surviving suspect in the Boston suburb of Watertown, ending a dramatic manhunt. The other suspect was killed in a shootout overnight with police.
The U.S. leader watched the fast-paced developments on television in the White House residence, then returned to the Oval Office where he was briefed by FBI Director Robert Mueller. Relief swept the White House at the news of Dzhokhar Tsarnaev’s arrest but there was no sign of a celebration.
