Sen. Al Franken is one of 15 original sponsors of the Charlie Morgan Military Spouses Equal Treatment Act, a bill that would extend VA benefits to legally-married same-sex couples. Currently, military couples who are legally married who live somewhere where same-sex marriage is illegal can be denied benefits. The bill was introduced in the U.S. Senate on Tuesday.

The bill is named after Charlie Morgan who died of breast cancer in 2013. Morgan’s wife was initially denied survivor benefits because the two were a married same-sex couple. According to Sen. Jeanne Shaheen, a Democrat from New Hampshire and the author of the bill, that inequality is unacceptable.

“No one who has served in uniform and fought for our country should be denied the benefits they’ve earned and deserve,” Shaheen said in a statement. “It’s unacceptable that a veteran could return home only to find that their families are not eligible for benefits they were promised because they live in a state that does not recognize same-sex marriage. We must act immediately to right this wrong.”

The bill faces a tough time in a Republican dominated Congress, but Shaheen hopes to amend the bill to a piece of legislation that has already passed the House. In addition to Shaheen and Franken, the bill is also being sponsored by Senators Kirsten Gillibrand (D-NY), Richard Blumenthal (D-CT), Sherrod Brown (D-OH), Patrick Leahy (D-VT), Ed Markey (D-MA), Chris Coons (D-DE), Ron Wyden (D-OR), Chris Murphy (D-CT), Dick Durbin (D-IL), Brian Schatz (D-HI), Sheldon Whitehouse (D-RI), Tammy Baldwin (D-WI), Mazie Hirono (D-HI), and Gary Peters (D-MI).
