The Washington Nationals have banned at least one spectator after a white nationalist banner was displayed during Sunday’s game against the Baltimore Orioles at Nationals Park. Team officials said the incident happened during the fourth inning as part of the club’s “Salute to Service” event, which honors military members and veterans during home games. The banner carried political and anti-immigration messages along with the name of a white nationalist website. It also included the phrases “SAVE AMERICA” and “DEPORT 100+ MILLION” before stadium staff quickly moved to remove it. According to the Nationals, an usher attempted to take down the banner after spotting it in the upper deck area of the stadium. However, the people holding the sign resisted efforts to confiscate it and then fled the scene. A spokesperson for the Nationals said the organization has identified at least one person connected to the banner and has permanently banned that individual from returning to the ballpark. The team also confirmed it is working with police in Washington, DC, as part of an ongoing investigation into the incident. In a public statement, the Nationals strongly condemned the display and said hateful language and discrimination have no place at the stadium. The organization said it wants Nationals Park to remain a safe and welcoming place for all fans, families, and visitors attending games. The incident happened during a game the Nationals lost 7-3 to the Orioles. While the game continued without interruption, the banner quickly drew attention online after videos and photos spread across social media platforms. The Nationals have rules regarding banners and signs brought into the stadium. Most approved signs must relate to baseball or contain family-friendly messages such as birthdays, anniversaries, or supportive greetings. The team’s policy does not allow offensive or hateful content inside the venue. Reports said three individuals were involved in displaying the banner. Stadium security attempted to intervene moments after it appeared. Officials have not yet released the names of the people connected to the incident. Jake Lang later claimed responsibility for the banner on social media. Lang is known for his involvement in the January 6 Capitol riot and has built a following online through conservative political content. However, authorities have not publicly confirmed whether Lang personally attended the game or helped organize the display inside the stadium. The incident has renewed discussion about security procedures at major sporting venues across the United States. According to reports, it remains unclear how the banner passed through stadium security before the game. Experts noted that security screening systems at many stadiums are designed mainly to detect weapons and dangerous objects rather than fabric signs or banners. Modern stadium magnetometers can identify metal items and security threats, but soft materials like nylon banners often pass through without triggering alarms. Sports organizations across the country have faced growing pressure to respond quickly to political extremism and hate-related incidents at public events. Many teams have adopted stronger fan conduct policies in recent years to prevent racist, discriminatory, or threatening behavior inside arenas and stadiums. Major League Baseball teams have also increased efforts to promote inclusion and community outreach programs aimed at making games more welcoming for diverse audiences. The Nationals said they will continue reviewing the situation and cooperate fully with law enforcement officials. The club has not announced whether additional spectators could face punishment as investigators continue reviewing stadium footage and witness reports. The controversy comes at a time when sports leagues across the United States are paying closer attention to crowd behavior and fan safety during live events. For now, the Nationals say they remain committed to keeping hateful messages out of the stadium while ensuring fans can enjoy games in a respectful environment.
