US congressional support builds for Rwandan opposition leader Diane Rwigara

CNN -- A group of members of the US Congress are calling on the Rwandan government to drop charges against Diane Rwigara, a fierce government critic who is facing up to 22 years in prison on charges of incitement and fraud.

Rwigara, 37, has long said that the charges against her are politically motivated and stem from her bid to run against President Paul Kagame in the 2017 elections.
