Venezuelan opposition leader Juan Guaidó says he is not seeking political asylum in the U.S. and has not ruled out the possibility of running in a presidential primary.

Venezuelan opposition leader Juan Guaidó says he has crossed the border into Colombia on foot to seek a meeting with international delegations gathering there for a conference focused on his country’s political crisis.
