Hillary Clinton is the first presidential candidate -- or first U.S. political candidate of any sort -- to get a Snapchat Lens.

Snapchat users on Monday will be offered a lens that morphs them into Clinton lookalikes, part of an ad buy from pro-Clinton Super PAC Priorities USA, according to Snapchat.

Both Clinton and Trump advocates will have a presence on the video messaging app as Election Day looms.

There are three types of ads that candidates can buy: typical 10-second video ads, filters that people lay on top of selfies, and lenses, which are animated filters.

The Clinton campaign is buying a filter with the message "I'm with her," and the Trump camp has a filter of its own coming Tuesday.

On Monday, Snapchat said in a press release, that filters reach 40 % to 60 % of U.S. users. There are about 60 million daily U.S. users.

Other campaigns running ads on the app, include John McCain of Arizona, Chuck Grassley of Iowa, and Kelly Ayotte of New Hampshire.

Bernie Sanders' presidential campaign bought Snapchat geofilters in April to support its get-out-the-vote-efforts on the state's primary voting day.
