(CNN) Outgoing acting Homeland Security Secretary Kevin McAleenan announced on Thursday the restoration of previously frozen foreign aid to the Northern Triangle countries of Guatemala, Honduras and El Salvador.

"I have confidence that we will continue to take the necessary steps to establish a regional framework for migration management and a safer, more secure region," said McAleenan, who was in El Salvador for the announcement Thursday.

McAleenan, along with the State Department, recommended to the White House that aid be reinstated for specific programs, according to a source familiar with the request. The White House agreed it was the right path forward.

The source said $143 million would be released in targeted foreign aid, a partial reinstatement of the initial freeze.

McAleenan, a proponent of investment in the region, announced last week that he will step down. He is expected to depart by the end of the month.
