A group of protesting truckers missed a scheduled stop at the National World War II Memorial Friday afternoon after encountering unexpected traffic and heavy rain.

Organizers for the group were scheduled to meet members of Congress at the memorial at 11:30 a.m. on Friday after circling the Washington D.C. I-495 Beltway.

Multiple police officers on motorcycles were present at the memorial before the meeting was scheduled to take place — but they soon left the site when no one arrived.

Rep. Louie Gohmert, R-Texas, arrived at the scene along with a group of veterans who were visiting the memorial.

The group of veterans took a photo at the memorial in the pouring rain before leaving the site.

Three park rangers were stationed at the barriers, but were welcoming to all visitors who passed through the gates.

When asked by puzzled tourists about the signs and barriers, the park rangers explained that anyone who wanted to express their First Amendment rights at the memorial were allowed in.

An organizer at the memorial who was connected with the group admitted that the truckers on the highway were delayed by traffic and were regrouping at a rest area nearby. By 12:30 p.m., however, curious spectators and members of the media left the scene.

As Gohmert left, he explained that he had been prepared to meet with the truckers in the rain, but had to travel elsewhere in D.C. with the group of veterans.

The highway protest drew about two dozen participants, according to local reports.
