President Obama called for unity in America during a live-streamed speech on July 12 after the deadly shooting of police officers in Dallas.
Obama visited the city five days after a deadly sniper attack killed five officers during a protest against police shootings. Seven other officers were injured, as well as two civilians.
The president spoke at an interfaith memorial service at the Morton H. Meyerson Symphony Center in front of families of the fallen police officers and members of the Dallas community.
Michelle Obama, Vice President Joe Biden and wife Jill Biden, along with former President George W. Bush and former First Lady Laura Bush, were also in attendance.
Obama also commended the Dallas Police Department for the decrease in murder rates over the past years, as well as fewer cases of excessive force.
"Dallas Police Department has been doing it the right way," he said.
Obama noted an "overwhelmingly" large number of police officers are doing a good job, and agreed with Dallas Police Chief David Brown's remarks on Monday on how people ask the police force to do too much.
He also spoke of the racial divide in America, saying that discrimination didn't vanish after segregation and that bias remains, calling for unity.
Obama said people are mourning for the slain officers, as well as Alton Sterling and Philando Castile, who were both killed in police shootings last week.
Former President George W. Bush also spoke in his home state.
"Those of us who love Dallas and call it home have lost five members of the family," he said.
Dallas Mayor Michael Rawlings spoke about the strength of his city, while Police Chief Brown recited the Stevie Wonder song "I'll Be Loving You Always."
The Obamas were scheduled to meet privately with families of the police officers who were killed, and talk to those who were injured.
Meanwhile, in a surprising show of unification, Sen. Ted Cruz (R-Texas) traveled to Dallas with President Barack Obama aboard Air Force One on Tuesday, the senator's office confirmed.
