When Mitt Romney's campaign plane arrived in Las Vegas on Tuesday, it was parked in awkwardly close proximity to Donald Trump's private plane.
Trump, of course, is a Romney supporter who has been causing headaches for the presumptive GOP presidential nominee's campaign. On Tuesday morning, Trump went on CNBC, calling "birtherism" the "most important thing" in this presidential race. The Obama campaign has criticized Romney for not distancing himself from Trump. In fact, both men are in Las Vegas for a fundraiser that Trump is hosting.
