Europe’s victory came amid torrents of verbal abuse from a New York crowd which was heavily criticised for its behaviour.<\/p>\n
American great Tom Watson, the eight-time major champion who twice led the US team in 1993 and 2014, said he was “ashamed” of the unruly scenes.<\/p>\n
“I’d like to apologise for the rude and mean-spirited behaviour from our American crowd at Bethpage,” said 76-year-old Watson.<\/p>\n
European talisman Rory McIlroy was the prime target from the American galleries, while his wife Erica was hit by a drinks cup flung from one of the stands.<\/p>\n
After sealing victory on Sunday, McIlroy said the level of the personal insults was unacceptable.<\/p>\n
BBC Sport has contacted New York State Police for figures of any arrest and ejections over the weekend.<\/p>\n
“[The behaviour] needs to be talked about and needs to be addressed,” said Donald, who praised police officers for their handling of a febrile situation.<\/p>\n
“I don’t know how you rein it in, the odd people who shout. It is a tricky one. <\/p>\n
“We would love to just play and the US players were great on trying to quieten crowd.<\/p>\n
“Many Americans were coming up to say they how embarrassed they were for some of their fans. It was a small subset and don’t know how you control it.”<\/p>\n
While Watson was gracious on social media, there has not been an official apology from the US team.<\/p>\n
However, Donald thanked US counterpart Keegan Bradley and his players for attempting to ask the crowd to show respect.<\/p>\n
“I think the Americans were acting in the right way,” said Donald. <\/p>\n
“They understand they want the crowd to support them but not to be vitriolic against us.”<\/p>\n
BBC Sport has contacted the PGA of America – which organised the tournament – for a response to Donald and McIlroy’s comments.<\/p>\n<\/div>\n
