Mr Donald Trump celebrated his 70th birthday on Tuesday.
His presidential campaign is his first bid for public office and, if he wins in November, he will be the oldest person ever elected to a first term as president.
USA Today looked at some 70 of his quotes since 1984, which it said epitomised "the man, the brand, the provocateur and the potential president". Here we look at some of them.
