President Trump has blacklisted a former White House aide from managing his rallies, apparently over concerns about how the optics of his campaign-style event in Phoenix were handled last week.

Sources confirmed to Fox News that George Gigicos, a former White House aide who was working the rally as a Republican National Committee contractor, is no longer working for Trump following the Phoenix event.

Bloomberg first reported that Trump was unhappy with how the event looked, as media coverage initially showed the venue not quite filled. Bloomberg reported that Gigicos was later informed he’d never manage a Trump rally again.

If Trump was unhappy about the images of the crowd, he didn’t show it.

He tweeted last Tuesday about the “beautiful turnout.” And during a press conference Monday, Trump noted the “massive crowd” he had in Phoenix.

During the rally itself, Trump tore into the mainstream media for their coverage of his response to the Charlottesville violence, while also upping the stakes in his quest for a border wall, threatening to force a government shutdown if Congress won’t appropriate the funding.

But Bloomberg reported that there were issues with how the space in the venue was filled, even though supporters filled in as other speakers warmed up the audience.

One local official pegged the indoor crowd size at about 10,000. Gigicos previously served as White House director of advance.
