Appearing on a popular late night TV show, US President Barack Obama read out nasty tweets from Republican presidential nominee Donald Trump who is aspiring to succeed him at the White House next January.
"President Obama will go down as perhaps the worst president in the history of the United States!" Obama read appearing on the ABC's Jimmy Kimmel Live.
The president said his morning wakeup time is 7 am. He was responding to a question about when somebody has to call him in the middle of the night to tell him about an emergency.
He was asked why people don't trust his former Secretary of State, Hillary Clinton.
"A lot of this just has to do with the fact that she has been in the trenches, in the arena for 30 years, and when you have been in the public eye for that long, and in politics, folks go after you and they're trying to find a weak spot, and any mistake that you make ends up being magnifieda narrative begins to build," he said.
"The brand of politics that Hillary represents, which is pragmatic and says that you don't get everything done at once, you make progress and move pieces at a time, that may not attract as much attention, it's not something that goes into 140 characters...but I think she will be an outstanding president," Obama said.
Later, when asked if he wishes he were the one campaigning against Trump, Obama said, "I think Hillary's doing just fine".
Obama said he does have an iPhone but he can only access emails on it.
"I now have an iPhone, but it is, you know, like, the phone you give your 2-year-old, where they can pretend to press things, but nothing actually happens? So my phone has no phone, no camera, no music all it has is the Internet, and I can send e-mails," he said.
