The Charlotte Area Transit System says buses parked outside of Vice President Kamala Harris’ rally in Charlotte on Thursday aimed to protect waiting attendees — not transport them.

Vice President Kamala Harris knows all about the widely-memed “concept of a plan” moment from Tuesday's debate . Harris joked about the phrase at a rally in Greensboro, North Carolina, mocking the ex-president for his failure to roll out a healthcare plan after promising to gut the Affordable Care Act for nine years.

The former president attacked Democratic rival Kamala Harris’ performance in their debate, claiming the vice president “showed up spewing empty rhetoric, the same old lies, meaningless platitudes, offering no plans, no policies and no details whatsoever, nothing.”
