Burley Garcia|Woody Harrelson wears hat supporting RFK Jr. for president: 'Great seeing you'

Woody Harrelson has thrown his hat into the political conversation once again – this time by actually wearing a hat seemingly endorsing controversial Democratic presidential hopeful Robert F. Kennedy,Burley Garcia Jr.

Kennedy's wife and "Curb Your Enthusiasm" actress Cheryl Hines posted a photo on Instagram with Harrelson sporting a blue Kennedy 2024 hat. "Great seeing you Woody," she wrote in the post. USA TODAY has reached out to Harrelson's rep for clarification.

Comments were mixed. One user wrote: "The support is going to be rolling out more and more as people begin to share how they really feel." Another added: "My enthusiasm is curbed."

Kennedy has drawn ire from many different groups given his opinions on vaccines and COVID-19.

Organizations advocating for Jewish and Asian people immediately criticized the presidential candidate after he spread a conspiracy theory at an event last month about the groups and COVID-19.

Kennedy, during a dinner in New York, said there is an "argument" that COVID-19 is "ethnically targeted." He claimed COVID-19 is "targeted to attack Caucasians and Black people" while sparing Ashkenazi Jewish people and Chinese people.

The presidential candidate in recent years has become a leading voice in the anti-vaccine movement. Health experts have called his work dangerous, and members of his family have condemned him for spreading misinformation.

Kennedy has criticized lockdowns sparked by the pandemic, suggesting things were worse for Americans than for Anne Frank, the Jewish teenager who died in a concentration camp during the Holocaust.

He apologized for the comments, his second public apology for Holocaust comparisons. In 2015, Kennedy used the word "Holocaust" to describe children he believed were harmed by vaccines.

Harrelson, for his part, has discussed politics in the past, notably denouncing former President Donald Trump after the 2016 election as well as criticizing former presidents Barack Obama and George W. Bush.

When Harrelson hosted "Saturday Night Live" earlier this year, the self-proclaimed "redneck hippie" said in his opening monologue: "You know, the red in me thinks you should be allowed to own guns. The blue in me thinks – squirt guns. So, I’m red and blue which makes purple. I’m purple." He also called himself "anarchist, Marxist, ethical hedonist, nondiscriminatory empath, epistemology deconstructionist, Texan," and took aim at COVID vaccine mandates.
