Washington, Oct 28 (IANS): President Barack Obama will campaign for Democratic nominee Hillary Clinton almost everyday in the final week leading to the November 8 election, a White House aide said.

Obama will also ramp up his efforts to boost Democrats in down-ballot races through additional travel, robocalls, radio spots and endorsements, the aide said on Thursday.

He will court the millennial vote through late-night shows and online outlets. He's scheduled to appear on "Full Frontal With Samantha Bee" on October 31, ABC News reported

The aide said the president plans to focus on positive messaging, making his case for Clinton and looking forward to uniting the country after the divisive election.

But he will also continue to speak out against Republican nominee Donald Trump's claims that the election is rigged.

Obama will returns to Florida on Friday where he has not only tried to bolster Clinton, but also seemed all too eager to take aim at Republican Senator Marco Rubio, who is being challenged by Democratic Representative Patrick Murphy, the aide added.
