Minnesota representatives in Washington are calling on the VA to make a fix to problems with its billing system.

Senator Amy Klobuchar and Representative John Kline, penned the bi-partisan letter, which was co-signed by Senator Al Franken, Congressman Tim Walz, and six others.

The letter asks the VA to fix issues that resulted in the VA billing Minnesota Veterans for thousands of dollars of co-pays from as long as five years ago.

Lawmakers wrote that the sudden debt was caused by "the VA's inability to properly track, record, and bill for services."

Co-pays ranging from one to three thousand dollars are expected to appear on veterans' upcoming monthly statements because they were not charged at the time of care.
