After a daylong manhunt that saw police searching door-to-door through Boston, law enforcement officials captured the remaining suspect believed to be responsible for Monday's bombing at the finish line of the Boston Marathon. He was ultimately found in Watertown, Massachusetts.

In a statement from the James Brady Briefing Room after the arrest, President Obama commended the response from the state and local police and federal investigators.

"We owe a tremendous debt of gratitude to all our outstanding law enforcement professionals," he said. "These men and women get up every day, they put on that uniform; they risk their lives to keep us safe -- and as this week showed, they don't always know what to expect. So our thoughts are with those who were wounded in pursuit of the suspects and we pray for their full recovery."

While tonight's arrest closes one chapter in this tragedy, we're still left with many questions about these young men. President Obama pledged to put the full weight of the federal government behind finding answers.

"I've instructed the FBI and the Department of Homeland Security and our intelligence community to continue to deploy all the necessary resources to support the investigation, to collect intelligence, and to protect our citizens," he said. "We will determine what happened. We will investigate any associations that these terrorists may have had. And we'll continue to do whatever we have to do to keep our people safe."

It's been a long week, and the events in Boston have in some ways overshadowed another tragedy -- the explosion that took the lives of at least 14 people in West, Texas and wounded more than 200. Before the President closed, he made sure to remind the people of that community that they hadn't been forgotten.

"Our thoughts, our prayers are with the people of West, Texas, where so many good people lost their lives; some lost their homes; many are injured; many are still missing," he said. "I've talked to Governor Perry and Mayor Muska and I've pledged that the people of West will have the resources that they need to recover and rebuild. And I want everybody in Texas to know that we will follow through with those commitments."

President Obama and First Lady Michelle Obama today were at Boston's Cathedral of the Holy Cross to attend Healing Our City, an interfaith service dedicated to those who were gravely wounded or killed in Monday’s bombing near the finish line of the Boston Marathon. 

In his remarks, the President paid tribute to those whose lives were taken by the bomb blasts on Boylston Street -- to Krystle Campbell, 29, who was "always smiling." And to Lingzi Lu, a 23-year-old graduate student from China who had come to "experience all this city has to offer." And finally to Martin Richard, the 8-year-old boy from Dorchester whose mother and sister remain in the hospital, fighting to recover from their own injuries. Martin, said President Obama, leaves us with two enduring images, 'forever smiling for his beloved Bruins, and forever expressing a wish he made on a blue poster board: 'No more hurting people. Peace.'"

President Obama also praised the people of Boston, a city both he and the First Lady once called home. Like thousands every year, the two lived there as students -- just one of the many reasons, the President said, that Boston has a hold on so many hearts. "Every fall, you welcome students from all across America and all across the globe, and every spring you graduate them back into the world -- a Boston diaspora that excels in every field of human endeavor," he said. "Year after year, you welcome the greatest talents in the arts and science, research -- you welcome them to your concert halls and your hospitals and your laboratories to exchange ideas and insights that draw this world together."

Following a briefing from FBI Director Mueller, Attorney General Holder, Secretary Napolitano, and homeland security advisor Lisa Monaco, President Obama went to the Brady Press Briefing Room to update Americans on developments in Boston, following two explosions at the finish line of the Boston Marathon on Monday afternoon. 

"We continue to mobilize and deploy all appropriate law enforcement resources to protect our citizens, and to investigate and to respond to this attack," the President said in a televised address. "Obviously our first thoughts this morning are with the victims, their families, and the city of Boston. We know that two explosions gravely wounded dozens of Americans, and took the lives of others, including a 8-year-old boy.

"This was a heinous and cowardly act. And given what we now know about what took place, the FBI is investigating it as an act of terrorism.  Any time bombs are used to target innocent civilians it is an act of terror. What we don’t yet know, however, is who carried out this attack, or why; whether it was planned and executed by a terrorist organization, foreign or domestic, or was the act of a malevolent individual."

Guns: On Thursday, President Obama traveled to Colorado to urge the American people to push Congress to vote on a set of common-sense proposals to help reduce gun violence. The President wants to close loopholes in the background check system to keep guns out of the hands of criminals and others who shouldn’t have them -- and prevent mass shootings like the one that killed 20 young children and six adults in Newtown, CT.

“If you want to buy a gun, whether it's from a licensed dealer or a private seller, you should at least have to pass a background check to show you're not a criminal or someone legally prohibited from buying one,” said the President. “And that's just common sense.”
