DENVER (AP) — Colorado Republican Rep. Mike Coffman says the Veterans Affairs Department has turned over documents to Congress in response to a subpoena demanding information about how the cost of a Denver-area VA hospital soared more than $1 billion over budget.

Coffman had said earlier Wednesday the VA failed to turn over any documents. About 30 minutes later, he said the VA gave the House Veterans Affairs Committee the documents on a CD shortly after 5 p.m. Washington time. Coffman said he didn’t immediately know whether the CD contained all the documents the committee wanted.

The hospital in suburban Denver is projected to cost nearly $1.7 billion. The VA conducted an internal investigation but denied previous requests from Coffman and other members of the Veterans Committee to see detailed results.
