While authorities continue to investigate a spate of suspicious packages sent to high-profile Democrats and others, at least one Bay Area transit agency and a party office in the South Bay are ramping up security.
BART is boosting the visible presence of its officers throughout the transit system, according to spokesperson Chris Filippi, who added that no specific threats have been made against the train system.
"As always we encourage our riders to contact BPD if they see anything suspicious," Filippi wrote in an email to NBC Bay Area. "If you see something, say something."
NBC Bay Area has also reached out to MUNI and the Golden Gate Bridge, Highway and Transportation District to check if they are making any changes to regular security protocol.
In the South Bay, the Santa Clara County Democratic Party decided to lock its front door and install a doorbell as a security measure. A sign on the door asks visitors to knock.
"Now it’s like, you have to look over your shoulder all the time. What’s going on? Who’s the person behind us?" party member Judy Pipkin said.

The state party reportedly sent letters to its members reminding them to be vigilant.
"We’ve been telling all our canvassers, people that are volunteering, that they have to take a little bit more precautions as to who they’re talking to and when they’re approaching front doors of people’s homes," Pipkin said.
Authorities have seized at least 10 suspicious packages addressed to former Vice President Joe Biden, former President Barack Obama, Hillary Clinton and others over the past few days.
