WASHINGTON (AP) — Sen. Mitch McConnell has issued a strong call for Burma to amend its constitution to allow opposition leader Aung San Suu Kyi to run for president and for the military to submit to civilian rule.

The leader of Senate Republicans has for years been the most influential voice in Congress on Burma policy. A longtime critic of the former ruling junta, he’s become supportive of the nation’s shift from military rule.

But McConnell told the Senate Thursday reforms appear to have stalled, leaving Burma’s commitment to democracy open to question.

He said failure to amend a constitutional provision that prohibits those such as Suu Kyi with immediate family members who are foreign nationals would “cast a pall” over the legitimacy of national elections in late 2015.
