Rudy Giuliani will reportedly have a very visible role in Trump's re-election campaign

Special Counsel Robert Mueller's investigation into 2016 Russian election interference may be — mostly — wrapped up, but that doesn't mean President Trump's personal lawyer, Rudy Giuliani, will be taking a step back from the spotlight, Politico reports.

Instead, it looks like the former New York City mayor will shift to a new role in Trump's re-election campaign. His job, essentially, will be to serve as a "warm-up act" for Trump, focusing mostly on attacking his opponents — he's already gone after former Vice President Joe Biden and current New York City Mayor Bill de Blasio.

The reaction from other White House about Giuliani's increased involvement with the campaign is mixed, but the consensus appears to be that the good will eventually outweigh the bad. While Giuliani is known for making bombastic statements that don't hold up to fact checks — he "can get sloppy with the details" one campaign adviser told Politico — he's also reportedly effective at calming down Trump, whom he has known for decades. Trump reportedly calls him "my Rudy" sometimes, a signifier of the trust he places in him. Giuliani also said he thinks he cans serve as a "useful surrogate" for Trump in "blue collar portions of expected battleground states," Politico writes.

"We view him as a necessary component to the overall picture, because there are frequently messages that the president absolutely needs and wants to get out and he serves that role ably and cheerfully," the a Trump adviser said. "That's the best way to characterize him. If there wasn't a Rudy Giuliani, we'd have to invent one." Read more at Politico.
