(KTEN) — Texas Rep. Pat Fallon (R-District 4) and 18 other Republican lawmakers sent a letter to President Biden voicing concern about how his new student loan relief plan could impact military recruitment.

"This is a grave concern for those of us on the Armed Services Committee and those of us that are responsible in Congress," Fallon said. "One of the key elements to attracting talent into the military — as we all know — is the GI Bill."

The GI Bill offers educational benefits to veterans. But now millions of students with outstanding loans will be eligible to have up to $20,000 of the total forgiven, jeopardizing the military incentive.

"After you have completed your service and received an honorable discharge, you will receive tuition reimbursement — 100 percent tuition reimbursement — at public institutions. You'll also receive a stipend," said attorney and Navy veteran Bryan White.

Fallon said the military is already struggling to fill its ranks.

"The Army missed their recruiting goals this year by 20,000 troops; the Navy only reached 89 percent of their recruiting goal; and the Air Force also missed their recruiting goal by several thousand," he said.

With education incentives no longer unique to the military, Fallon is looking elsewhere for solutions.

"We can work with the military in carving out funds to focus on attracting more talent," the congressman said.

The loan forgiveness program is expected to help mainly working and middle class borrowers, an updated report from an influential research group found. That's a shift from its earlier projection that more higher-income borrowers would benefit from basic loan forgiveness.

About 75% of the benefit will go to households making $88,000 or less per year, according to the Penn Wharton Budget Model analysis released last month.
