“It showed the incredible resilience, heroism, commitment and love of the people who responded to these tragedies,” said Biden at a fundraiser for Democrats in Detroit, Mich., according to reports.
“I wondered what in the heck are they doing? Were they running away from harm? They were running through it,” said Biden. They were running to a hospital. They were running to help their fellow runners and citizens watching. It was an instinct, sort of stamped in our DNA.”
Biden’s comments came a day after law enforcement officials ended an unprecedented manhunt in Boston to capture the surviving suspect in the Boston attack, Dzhokhar Tsarnaev, who remained hospitalized on Sunday.
He has yet to be charged in the bombings, with investigators still searching for a motive for the attack.
The arrest came after what Obama called “a tough week” which also saw gun control legislation falter in the Senate and a deadly blast at a plant in Texas which left a dozen dead and hundreds injured.
Biden, who had spearheaded the administration’s push for gun control legislation, said that retaking the GOP-controlled House would be key to efforts to pass such measures in the future.
Biden said that many senators said they were unwilling to back the gun control measures brought to the Senate floor last week because “even if we do this, it will never pass the House.”
The vice president said that despite his lobbying efforts, not one of the 15 senators he called gave him a “substantive reason” for failing to back gun control.
In his remarks, Biden did not mention the 2016 presidential contest.
