Critics argue Trump’s trip is a blatant example of blending presidential duties with promoting his family’s business interests.

The Royal and Ancient Golf Club of St Andrews, which organizes the Open, the world's oldest golf tournament, said in a statement shortly after the Jan. 6 Capitol attack that it had "no plans" to stage the Open at Turnberry and "will not do so in the foreseeable future."

Scotland is the birthplace of Trump’s mother and a place where he owns two golf resorts. Yet he hasn’t always had a warm reception there.
