Every four years, American citizens are given time to evaluate who they'd like to lead the country.

And naturally, as the 2020 presidential election between former Vice President Biden and President Trump draws closer, public figures have openly expressed their own beliefs regarding who should carry out the position.

Here's a look at some of the stars who have endorsed Biden and his vice presidential pick Kamala Harris for president in the 2020 election.

Baldwin recently endorsed Biden with an Instagram post celebrating World Mental Health Day, as she wore a T-shirt sporting the candidate's campaign logo.

"It’s world mental health day, and something that has affected my mental health is the state of our country and the future of our country," she wrote in the caption on Oct. 10. "I have hope, but we need to collectively make the change we want for our future and that means getting out there to VOTE!!!"

Her father, actor Stephen Baldwin, endorsed Trump the same day.

One of Hollywood's most revered actors has thrown his support behind the former vice president.

According to Deadline, Hanks appeared at a Biden campaign event alongside the politician geared toward low-dollar donors. Citing an invitation sent to supporters, the outlet reported that the event was referred to as "Grassroots Fest."

“Every election comes along, and you can always make the argument, ‘This is the most important election of our lives.’ This is the most important election in the history of America,” Hanks said at the event, according to Deadline.

Like Swift, Johnson hasn't been known for publicly endorsing candidates. In fact, he's toyed with the idea of running for office himself.

When Harris was selected as Biden's running mate, Perry gushed over the vice-presidential nominee, but she also said that she was representative of Biden's decision making.

"I’ve had the privilege of getting to know @kamalaharris over the years and @joebiden choosing her as his running mate is already a testament to his decision making: Kamala is exactly the kind of leader WITH experience we desperately need right now," wrote the singer alongside several pictures of herself with Harris. "She’s the type of person willing to put in the WORK to make our country better. Less than 3 months until Election Day. LET’S DO THIS Y'ALL."

In October, Schwarzenegger urged fans to vote for Biden while slamming President Trump’s "don’t be afraid of COVID" tweet.

“If that tweet itself is not enough to get you fired up to want to elect Biden and get rid of Trump as president of our country, then I don’t know what is,” Schwarzenegger said on her Instagram Stories, according to Yahoo! Entertainment.

“That’s the sickest tweet I’ve ever seen,” she wrote, per the outlet. “Please vote.”

He continued: "Don't just do it for Joe and Kamala. Do it for your little brother, your little sister. Do it for the next generation. Do it for the environment — for justice, for equality and just to end this insane chaos. Four more years of that? I don't think so."

“We want to talk about the most pressing problem in America today, and that is our leadership," Ford says in a video clip shared on Bloomberg’s Instagram. "We want to encourage people to support candidates that will support the environment."

“I looked around for an issue that we’re really emotionally connected with, one of the primary things is the protection of nature and the environment," Ford added.

The star went on to note that he believes Biden is “a centrist” and urged people to vote in favor of the candidate that plans to do something about climate change.

"He said — he believes in a coalition, he believes in consensus. That’s the Democratic Party,” Ford concluded.
