“We decided we would jump on 35 to show support for our president,” she said. “I didn’t see anyone being overly aggressive.”

On Twitter, Narvaiz wrote: “We sent the@JoeBiden @KamalaHarris bus out of Hays! Your kind aren’t welcome here!”

“We don’t want any of the values or policies that the Democratic Party is embracing,” she told the Tribune on Saturday. “We don’t want any of those in Texas.”

U.S. Rep. Lloyd Doggett disagreed, accusing President Trump of inciting “aggressive, abusive conduct.”

“Those who fear their party is about to lose Texas resort to such desperate tactics. We have to stand up to these bullies just as we seek to protect the right of every last Texan to vote out the Bully-in-Chief,” Doggett said in a statement to the Tribune.

Naranjo, chair of the Travis County Democratic Party, said she was on the phone with a staffer on the bus who alerted her that they were being closely followed by a group of Trump supporters.

According to Naranjo, the staffer on the bus told her a truck collided with one of the staff member vehicles. Neither of the vehicles stopped. The collision was partially caught on video and posted on Twitter. The video does not show how the collision began.

As the bus continued to pass through multiple jurisdictions in Hays County, different police departments received reports about the caravan.

In a statement, the city of Kyle said police received a report that two or more vehicles may have made contact on Friday around 4 p.m. Officers responded to the area but no vehicles stopped to share information with law enforcement.

“From videos of the event that have now surfaced on social media, it appears that the vehicle contact actually occurred within San Marcos, Texas, prior to the campaign bus arriving in Kyle,” a statement from the Kyle Police Department read. “All involved parties are being referred to the San Marcos Police Department should they desire to file any type of report with law enforcement.”

A San Marcos spokesperson said police received a call from the Biden campaign bus requesting a police escort but weren’t able to catch up to the bus before it exited the city due to traffic. The police have not spoken to either driver about the collision and said they weren’t able to determine who was at fault.

According to Hays County Sheriff Gary Cutler, the Biden campaign did not notify his office that it would be passing through the county to allow law enforcement to prepare for any possible confrontations. “The planning of this was questionable,” Cutler, a Republican running for reelection, said Tuesday.

Democratic officials say Trump supporters created a dangerous situation on Interstate 35 and continued following the bus into Austin.

Travis County Precinct 4 Constable George Morales was at the AFL-CIO parking lot at 11th and Lavaca streets for a planned press conference and said the group initially tried to step on the property, but law enforcement asked them to stay on the sidewalk. He said the group was aggressively shouting but did not get physical.

The press conference was canceled as well as a subsequent campaign event in Pflugerville with the Austin Young Dems due to safety concerns.

State Rep. Sheryl Cole (D-Austin) shared the cancellation on Twitter, calling it a “first for her.”

“Unfortunately, Pro-Trump Protestors have escalated well beyond safe limits. Sorry to all who looked forward to this fun event.”
