Professional golfer Phil Mickelson weighed in on the “No Kings” protests that took place nationwide on Saturday, taking a swipe at both the demonstrators and Joe Biden in a message shared on X.

Mickelson, 55, used his account on the platform to comment on the wave of anti-Trump protests held across multiple cities, which organizers said were intended to oppose what they described as authoritarianism.

The six-time major champion, who has publicly supported President Donald Trump in the past, used the occasion to mock both the protesters and Biden’s handling of executive authority.

“On this special day as we all gather to fight against blanket auto pen pardons and executive orders, lawlessness, and stealing citizen’s resources for illegal non citizens, I believe it has worked!! That is no longer happening so great job everyone,” Mickelson wrote.

The message appeared to reference the controversy surrounding Biden’s reported use of an autopen to authorize pardons and sign executive actions while in office.

Biden’s reliance on the device drew criticism from lawmakers and commentators who said it reflected a lack of engagement in presidential duties.

Mickelson’s post also came after Biden’s departure from the 2024 presidential race, which ended amid declining approval ratings and growing discontent within his own party.

His decision to withdraw from contention left Kamala Harris to lead the Democratic ticket through the final months of the election cycle.

Mickelson, who joined LIV Golf after a long career on the PGA Tour, has been outspoken about national and political issues in recent years.

His post on Saturday drew attention from both golf fans and political commentators who noted that it came during widespread demonstrations under the banner “No Kings.”

According to reports from Breitbart News and other outlets, the protests featured groups of anti-Trump demonstrators dressed in costumes and carrying signs with slogans opposing the current administration.

Protesters were seen wearing inflatable frog, cat, and dinosaur costumes while chanting against what they described as “authoritarian rule.”

The gatherings took place in several major U.S. cities, including Washington, D.C., New York, and Los Angeles.

The “No Kings” demonstrations, coordinated by left-leaning groups, were promoted online as a statement against “executive overreach.”

The events occurred during the ongoing partial government shutdown that began October 1, after the Senate failed to pass a funding resolution.

Mickelson’s message quickly went viral among conservative commentators who praised the golfer’s willingness to speak publicly on political issues.

The post also sparked pushback from critics who accused him of mocking legitimate protest activity.

The veteran golfer did not issue a follow-up statement, and his representatives did not immediately respond to requests for comment.

However, Mickelson’s public support for President Trump has been consistent.

He previously praised Trump’s approach to business and sports infrastructure, including the President’s role in developing golf resorts and hosting professional tournaments.

The “No Kings” protests were among several nationwide events organized in recent weeks by groups critical of Trump’s administration and Republican leadership in Congress.

Mickelson, a 45-time PGA Tour winner and one of golf’s most recognizable figures, remains active in LIV Golf competition and has frequently used his platform to discuss both the sport and national issues.
