Donald Trump's immediate and extended families are supporting his presidential bid, but daughter Ivanka's brother-in-law is not.

Josh Kushner, the 31-year-old brother of Jared, Ivanka Trump's husband, will not be backing the billionaire businessman come November. Jared Kushner's role in the Trump campaign has grown since it started 14 months ago.

Kushner's spokesman told Esquire he has been a lifelong member of the Democratic Party and plans to vote for Hillary Clinton even though his brother's wife's father is the Republican pick.

"Josh Kushner declined to comment on the record for this article; through a spokesman, he said that he loved his brother and did not want to say anything that might embarrass him. Nevertheless, the spokesman also said that Josh is a lifelong Democrat and will not be voting for Donald Trump in November," Esquire said Thursday.
