In addition to Lau, Warren chose another longtime aide, Dan Geldon, as her campaign’s chief of staff, according to a person familiar with the decision. Geldon is a former chief of staff in Warren’s Senate office.

The hires were first reported by The Boston Globe on Wednesday.

The decision to tap Lau to manage her presidential campaign is emblematic of Warren’s deep reliance on a tight-knit group of longtime aides.

“Roger and I have been together since my first days as a candidate for office, and it’s always been a fight from the heart. It’s what binds us together,” Warren said in a statement reported by the Globe.

“Roger believes in building a grassroots operation, and that’s exactly what we’ll do.”

The news of Warren's decision comes days after she formalized her 2020 presidential campaign, announcing at a rally on Saturday that she was officially jumping into the Democratic nominating contest.
