evidence: A Facebook post claims to be a letter by Hollywood star Clint Eastwood defending US President Donald Trump. The lengthy post is credited as "from Clint Eastwood" and begins, "I love when people call Trump Stupid." It then lists several of what it claims are Trump’s accomplishments before it going on to attack Hillary Clinton, Madonna, Robert DeNiro and Katy Perry by posing the question: "Are you sure you back a party that enables the decimation of every core principal (sic) of Christianity?" [...] Eastwood has previously described himself in interviews as a "libertarian" and expressed cautious support for the then presidential candidate Donald Trump in a 2016 interview with Esquire magazine, saying: "I can understand where he’s coming from, but I don’t always agree with it."
