I didn't know Maduro was responsible for protecting the US border. Perhaps he should be charged with "dereliction of duty"? To go along with his other trumped up charges (ha.. ha..) such as "possession of machine guns and other destructive devices".
There might be more than one reason for an ongoing crisis, and different takes on who’s responsible. However Maduro is responsible of huge number of refugees fleeing Venezuela, and we (and some other countries around) have some obligations to help asylum seekers.
