President Obama jabs at Donald Trump during appearance on Jimmy Kimmel Live

US President Barack Obama, who is currently on his farewell tour as his last term in office winds down, stopped by Jimmy Kimmel Live on Monday (24 October). The president participated in Kimmel's "Mean Tweets" segment and managed to take a swipe at Republican nominee Donald Trump.

Obama read a number of mean tweets about him before reading Trump's criticism. "President Obama will go down as perhaps the worst president in the history of the United States," Trump tweeted back in August.

"Well, @realDonaldTrump, at least I will go down as president," Obama quipped back. The witty remark was met with laughs from the audience and followed up with a phone drop from the president.

The president also answered the late night host's question about the GOP nominee's performance during the presidential debates. Obama said he laughed "most of the time" that Trump spoke. Obama also noted the difference between he and the Republican attempting to replace him. "I don't tweet at 3am about people who insult me," he said.

According to CNN, the visit was part of a campaign effort in support of his preferred successor, Hillary Clinton. White House spokesman Josh Earnest told reporters on Monday (24 October) that the president would be campaigning for Clinton during the final two weeks running up to the 8 November election.

"The president will spend a significant amount of time travelling next week in support of not just Secretary Clinton's presidential campaign, but Democrats further down the ballot, as well," Earnest said.

Trump seemed to ignore President Obama's comments and instead focused on tweeting against Obamacare. Recent reports noted that premiums for health insurance under the Affordable Care Act will rise 25% on average. The GOP nominee also encouraged his supporters to cast their ballots early.
