Donald Trump

The comments come as part of a sit-down interview with Erin Burnett, during which el-Sisi seemed to downplay a ban on Muslims entering the United States that, at times, served as a centerpiece to the Republican presidential nominee's political rise.

In an interview with Cosmopolitan magazine published Tuesday, the former first daughter said she was unmoved by the subject, which Trump alluded to in the final moments of Monday's first presidential debate and then more directly to reporters after the event.

The business magazine has reappraised the Republican White House hopeful's personal wealth and found it has haemorrhaged $800m since 2015.

Forbes now estimates the real estate magnate's net worth at $3.7bn (£2.7bn).

The publication said the decrease was mainly due to the "softening" of the New York property market.

Mr Trump, who once wrote a book called Midas Touch, has said the country needs a dealmaker-in-chief in the White House.

There was a moment in the first US presidential debate when lots of people asked themselves: "Did Trump just say 'bigly'?"

Followed quickly by: "Is that even a word?"

It came during a discussion on fiscal policy, when, Donald Trump told his opponent: "I'm going to cut taxes bigly, and you're going to raise taxes bigly." Or so many thought, anyway.

Jimmy Carter and Ronald Reagan's debate in 1980 drew 80.6 million viewers.The viewing figures only count those who watched the debate on the 13 US TV channels that carried it live, meaning the true figure may be much higher.

Millions are also thought to have watched worldwide through online live streams or in bars and at parties.

But Trump never openly insulted Clinton, never called her "Crooked Hillary", nor did he cross the stage at any point, as a former senate opponent famously did with Clinton in 2000 - a move that was seen as physically intimidating towards a female candidate.

Despite that, gender and sexism did feature prominently during several exchanges in the debate, and in the initial feedback on the candidates' performance on social media.

Now, 20 years later, she is back in the headlines.

Ms Machado claims she was called "Miss Piggy" by Donald Trump, the Republican candidate for the White House who owned the beauty pageant when she won it.

The remarks were made, the Venezuela-born model says, after she put on some weight following her win.

How did it come up?

The issue was brought up by Hillary Clinton, the Democratic presidential nominee, during Monday's televised debate with Mr Trump. She was making a point about her rival's remarks about women.

Mr Trump said he held back "because he didn't want to hurt anyone's feelings".

In a Fox News interview, he also accused moderator Lester Holt of being tougher on him than on Mrs Clinton.

Overnight polls with small samples were split on who won, but more rigorous surveys are due in the coming days.

Initial estimates from research firm Nielsen suggest more than 80 million Americans watched the debate at home, but that figure will rise significantly when other forms of viewing are counted.

That drubbing is similar to Mitt Romney's dominant performance over President Barack Obama in the first 2012 presidential debate.

Voters who watched said Clinton expressed her views more clearly than Trump and had a better understanding of the issues by a margin of more than 2-to-1. Clinton also was seen as having done a better job addressing concerns voters might have about her potential presidency by a 57% to 35% margin, and as the stronger leader by a 56% to 39% margin.

Perhaps we should call it "Smackdown at the Mack," since it is being held at the Hofstra University's David S. Mack Sports and Exhibition Complex on New York's Long Island.
