Drug trafficking major point of contention as Colombian president visits White House

Colombia's President Gustavo Petro is in Washington today for a visit with US President Donald Trump. The meeting follows months of barbs exchanged between the two leaders, including claims by Trump that the Petro is a "drug lord" and threatening military intervention. But, as the International Crisis Group's Elizabeth Dickinson told The World's Marco Werman, the two countries have long relied on each other to fight the drug trade.
