Former New York Mayor Rudy Giuliani is having his turn in the hot seat.
According to Business Insider, he appears to be the weakest link in President Donald Trump's chain.
Giuliani has been embroiled in Trump's dealings with Ukraine.
He's been implicated by several government officials as Trump's main envoy in an effort to solicit Ukraine's interference in the 2020 election.
He's also under criminal investigation by the US attorney's office in the Southern District of New York.
