Ivanka Trump could be the first female and Jewish president, according to her mother.Ivana Trump, US President Donald Trump's first wife, has been making the media rounds to promote her new memoir, Raising Trump. She suggested the president's daughter and trusted advisor may have too much on her plate in an interview with Time on Tuesday.But, the president's first wife said, she isn't ruling out the possibility that Ivanka Trump would pursue a future career in politics.“I think Ivanka played a big part in Donald’s victory. Voters looked at her and thought, I like her. I trust her. She loves her father, so he can’t be that bad. Who knows? One day, she might be the first female — and Jewish — POTUS,” read an excerpt from the memoir published by Time.This isn't the first time Ivana Trump's name appeared in the news this week.The president's current wife, Melania Trump, had a message for her on Monday: Enough with the self-serving comments.The first lady was responding to Ivana Trump's interview on ABC's "Good Morning America" program, in which she jokingly referred to herself as first lady."I have the direct number to White House but I don't really want to call him there because Melania is there," the Czech-American, who was married to Donald Trump from 1977 to 1992, told ABC. "I don't really want to cause any kind of jealousy or something like that because I'm basically first Trump wife, OK? I'm first lady, OK?"Melania Trump's spokeswoman issued a statement that mentioned her son with Donald Trump, Barron."Mrs. Trump has made the White House a home for Barron and the President. She loves living in Washington, DC and is honored by her role as First Lady of the United States. She plans to use her title and role to help children, not sell books," the statement said."There is clearly no substance to this statement from an ex, this is unfortunately only attention-seeking and self-serving noise."It was unclear whether the president was aware of the fracas. He was playing golf on Monday with Republican Senator Lindsey Graham.
