venezuelan opposition attempted to bring humanitarian aid in from columbia. venezuelan president nicholas mendoza. the shipment was part of a u. s. clock to overthrow his government. alexander, i'm casey, has the latest now from the colombian capital overtime. the relationship between the 2 countries have been essentially shut for now over 3 years. but actually trade between the 2 countries that practically been halted since 2015. when the 2 countries 1st shut the border due to political attentions. it's significant. first of all, 4 venezuelans who need to cross into columbia for good for health services education services. most of them had so far to try and do that through illegal paths that were controlled and are controlled by a criminal group at to border. so hopefully they'll now be able to cross into columbia legally that will also help migrants. you know that the large number of venezuelan migrants crossing to columbia, they will also be able, hopefully to do so on the bridge. and then obviously it's important politically because this can be see as a 1st step to try and resume relationship
