Captain America by name, Captain America by nature.

When Chris Evans isn't busy defending the planet from intergalactic threats, he's out policing the digital highways of Twitter -- shutting down Trump's tweets about global warming, and criticising the president's relationship with Putin.

On Wednesday, however, the Marvel actor set his sights on a different target: Fox Nation host and right-wing political commentator Tomi Lahren.

Lahren has spent much of the past couple of days live-tweeting CNN's Democratic debates, attacking the various candidates and angrily tweeting about immigration. At one point during the first debate, she tweeted this:

At the time of writing, that tweet has almost 29,000 responses. Unsurprisingly, many outraged people were quick to fill Lahren's replies with counter-arguments.

On Wednesday, Evans joined their ranks.

Evans' decision to respond to Lahren's tweet isn't a big surprise. The actor is very politically active, and not just on Twitter.

Earlier in the year it was revealed that he has a political website in the works, which Evans described as a "civic engagement project" that will aim to help people understand various issues affecting the U.S. and beyond. Sign us up.
