Pompeo accuses former U.S. Vice President Biden of corruption over Ukraine dust-up

U.S. Secretary of State Mike Pompeo on Sunday accused President Donald Trump's Democratic political rival Joe Biden of improperly intervening to protect his son from an investigation in Ukraine.

Former Vice President Joe Biden "behaved inappropriately," Pompeo said on ABC's "This Week," adding that he intervened "in a way that was corrupt" and that Biden's actions should be investigated.
