the white house is defending president trump's decision to pardon former arizona sheriff joe arpaio. >> i think there's a clemency argument that can be made for the long history of service, both in the united states military and in law enforcement for the sheriff. i think the president's been pretty clear. it's pretty straight forward that he believes that that long history of service merits this clemency and he's acted accordingly. >> now, his reaction comes just hours after this washington post report. as joseph arpaio's federal case headed towards trial, the president asked attorney general jeff sessions whether it would be possible for the government to drop the criminal case against arpaio but was advised that would be inappropriate. joining me now, catkatie bo
