(Reuters) -President Donald Trump's super powers as a public figure have long included the ability to redirect, evade and deny.

Trump has scolded reporters, claimed ignorance and offered distractions in an effort to quash questions about Epstein and the suspicions still swirling around the disgraced financier's case years after his 2019 death in prison.
