ATLANTA -- U.S. Attorney General Jeff Sessions told law enforcement officials that child exploitation is becoming more widespread throughout the nation.

Session was in Atlanta to speak before the National Law Enforcement Conference on Human Exploitation.

Sessions, a former prosecutor, said predators have an easier path to reach children through phones and tablets.

Sessions didn't address President Donald Trump's criticism of the Department of Justice's legal strategy to defend a travel ban before the Supreme Court. Trump made the comments Monday on Twitter.

"We saw the power of teamwork recently here in Georgia and in my home state of Alabama," Sessions said. "Last November, the Alabama and Georgia Internet Crimes Against Children task forces coordinated an investigation called Operation Southern Impact.

"It resulted in the arrest of 29 suspects from both states on charges of possession and distribution of child pornography, and the seizure of 731 digital devices as evidence," Sessions said. "The investigation included more than 70 federal, state, and local law enforcement agencies.

"That is the kind of teamwork it takes to find these predators and bring them to justice."

The 2017 National Law Enforcement Training on Child Exploitation is a national training event to expand the efforts and knowledge base of law enforcement investigators and prosecutors by providing specialized training focused on investigating and prosecuting technology-facilitated crimes against children.

Last year, then-Attorney General Loretta Lynch spoke before the group in Atlanta.
