Turns out, reality is a little different. That was BEFORE guilty verdicts and indictments starting happening. NBC has this report today...
With the possibility now looming that the president himself could be subject to an interview by the FBI or Mueller’s investigators, Trump’s legal team has been debating whether it would be possible to simply avoid it. One individual familiar with the strategy said those internal discussions within Trump’s legal team began shortly after the president’s former campaign manager, Paul Manafort, was indicted in late October for money laundering in connection with his business dealings with Ukraine.
In addition to the possibility of suggesting the president submit written responses in place of an interview, a second person familiar with the president’s legal strategy said another possibility being contemplated was an affidavit signed by the president affirming he was innocent of any wrongdoing and denying any collusion. It was not clear what such an affidavit might state regarding the president’s firing of former FBI Director James Comey in May 2017 at a time when Comey was leading the Russia probe.
It's not like he's never been questioned or deposed before. Remember, he's been sued more than 3000 times.
