Not even Glenn Beck — the conservative radio host who reportedly spent $500,000 on travel stumping for Ted Cruz during the Republican primaries — is ready to let the Texas senator off the hook for endorsing Donald Trump. In an interview on Beck's radio show Monday, Beck repeatedly tried to get Cruz to explain his decision to vote for Trump — despite the fact that during the Republican National Convention, Cruz used his speech to advise Americans to "vote your conscience" rather than to endorse the GOP nominee. At first Cruz tried to paint his convention speech as a way to "lay out a path to uniting Republicans," explaining that this election is "a binary choice" and Hillary Clinton isn't the choice to make.
