The Trump-Pence campaign's latest sales pitch: Columbus Day

Want to Make America Great Again? Then buy a hat today.

That's the underlying message behind a Monday email sent out to supporters of the Trump-Pence 2020 campaign, in honor of Columbus Day.

"The media and the Left have been working overtime to undermine our history," the email reads. "That's why we wanted to have a HUGE celebration this Columbus Day -- to show them we're not going to let them get away with it."
