White House infrastructure policy adviser DJ Gribbin is leaving his post.
Gribbin, who joined the Trump administration in February 2017, is "moving on to new opportunities," a White House official said.
The soon-to-be-departed staffer held a key role in defending the administration's infrastructure plan _ which has stalled in Congress.
"Since he joined the team early last year, DJ has played an important part in coordinating the Administration-wide process behind the President's infrastructure initiative," national economic adviser Gary Cohn, who is also leaving the White House, said in a statement Tuesday.
"I am grateful for his service and fully believe that the plan President Trump delivered to Congress, combined with the work we are doing administratively, will have a transformational impact on our economy," Cohn said.
The administration proposed an infrastructure revamp that was met with resistance by both Democrats and Republicans _ who were skeptical of the government's ability to fund the overhaul.
