Former speech writer for President George W. Bush, David Frum, joins Ari Melber to discuss breaking news from the Washington Post that reports Pence claims he had no knowledge of the plot with Ukraine to get dirt on the Bidens. Frum argues the WaPo reporting shows Trump “is not so reckless to let us VP remain clear,” adding the “harrowing circumstance” forces Trump to “make sure that the vice president is as dirty as possible, to make sure that their interests are aligned.” Aired on 10/02/19.
