President Trump was "very upset" when Amanda Knox, an American accused and later cleared of a murder charge while studying abroad in Italy, did not back him in the election, a friend of Trump says.

The New York Times on Friday profiled George Guido Lombardi, a neighbor of Trump's in Manhattan.

Trump tweeted about his belief of Knox's innocence twice in 2011, writing shortly before her verdict that "Everyone should boycott Italy if Amanda Knox is not freed—she is totally innocent” and backing her in interviews.

Knox was initially convicted on charges of murdering her Italian roommate, although some legal experts questioned the prosecution's case. Knox successfully appealed to the highest court in Italy, which ultimately exonerated her.

During the 2016 campaign, Knox wrote on her blog about her support for Clinton, calling Trump a "destabilizing agent" and criticizing his stance on abortion.

The Times profile centers on Lombardi's ties to Trump and to key populist figures in Europe.
