Multiple news outlets on Friday morning identified the Dallas shooting suspect killed by police as Micah Xavier Johnson, citing various law enforcement sources.

Dallas police have not yet publicly confirmed the identity of the suspect.

In an extraordinary move, police in Dallas used a bomb and a robot to kill a suspect in the deadly Dallas shooting early Friday morning.

Faced with a suspect holed up at El Centro College in Dallas and several officers already dead, law enforcement turned to the unusual method of detonating a bomb.

After five law enforcement officers were killed when snipers opened fire on police at the scene of a Black Lives Matter protest in Dallas on Thursday night, the organizers of the protest condemned the violence.

Gunshots rang out as the protest, scheduled to last two hours, was wrapping up around 9 p.m. CT. It had been peaceful to that point, and the Dallas Police Department had been tweeting photos from the scene, including pictures of officers posing with protestors.

Dominique Alexander, the president of the Next Generation Action Network, told NPR in a statement that the group "does not condone violence against any human being, and we condemn anyone who wants to commit violence."

Dallas authorities will hold a news conference Friday at 8:30 a.m. ET to provide updates on the deadly shooting of five police officers in Dallas.

President Obama early Friday morning addressed the deadly shooting of police officers in Dallas, saying he was "horrified" by the attack.

"We still don't know all the facts. What we do know is that there has been a vicious, calculated and despicable attack on law enforcement," Obama said in an address in Warsaw, Poland, where he is attending a NATO summit.

Throughout his testimony Thursday before the House oversight committee, FBI Director James Comey defended his decision not to recommend criminal charges against Hillary Clinton arising from her use of a private email server. But he also gave House Republicans some material to work with in attacking Clinton and the way she handled classified information as secretary of state.

During the House oversight hearing with FBI Director James Comey on Thursday, Rep. Thomas Massie (R-KY) suggested that the FBI launch an investigation into the people who sent classified information to Hillary Clinton over email.

Comey told Massie that in some of the cases where classified information wound up on Clinton's private server, staff had forwarded the information in a chain of emails until it eventually reached Clinton herself.

Rep. Jason Chaffetz (R-UT), the chair of the House Oversight and Government Reform Committee, on Thursday morning quizzed FBI Director James Comey on whether Hillary Clinton lied about her email use and told Comey that he would like the FBI to review Clinton's testimony to Congress.

During his line of questioning with Comey, Chaffetz first attempted to establish whether Clinton received classified information on her private email server. Comey confirmed that she did, which he had already spelled out in his Tuesday statement.

FBI Director James Comey opened his Thursday testimony before the House Oversight and Government Reform Committee with a fierce defense of his decision not to recommend prosecuting Hillary Clinton for mishandling classified information.

"I hope at the end of the day, people can disagree, can agree, but they will at least understand that the decision was made and the recommendation was made the way you would want it to be, by people who didn't give a hoot about politics, but who cared about what are the facts, what is the law, and how have similar people, all people, been treated in the past," Comey said.
