WASHINGTON — New research linking veterans’ high blood pressure with wartime exposure to chemical defoliants could dramatically expand federal disability benefits for tens of thousands of Vietnam-era troops.

The findings, from the National Academies of Sciences, Engineering and Medicine, conclude that “sufficient evidence” exists linking hypertension and related illnesses in veterans to Agent Orange and other defoliants used in Vietnam, Thailand and South Korea in the 1960s and 1970s.
