“While we strongly support your plans to increase funding for the VA by $25 billion over the next five years,” the letter reads, “it is with equal conviction that we oppose the proposal to bill veterans’ private health insurance plans for care and treatment of service-connected injuries or disabilities.”

Rep. Ann Kirkpatrick (D-Ariz.) is leading a similar effort in coordination with Nye. Her letter is even more forcefully worded, calling the White House proposal “deeply troubling” and charging that it “ignores the mission of the VA.”
