Nobel winner Maria Corina Machado says will return to end Venezuela 'tyranny'

Nobel Peace Prize winner Maria Corina Machado said in a surprise appearance Thursday that she would do her "best" to return to Venezuela to end the "tyranny" in the country. "I will not say when that is or how it's going to be," she commented, but added that she wanted "to end with this tyranny very soon and have a free Venezuela".
