Harris preparing for upcoming Trump debate in battleground Pennsylvania

It includes five days in Pittsburgh and a Trump stand-in wearing a wig.

Choosing to stay in Pennsylvania, a critical battleground state, could potentially allow Harris to continue campaigning while she prepares for the debate -- and what will be her first in-person meeting with Trump.

The debate is a critical moment for Harris as it could be her last opportunity to pitch herself to a large television audience.

Reines isn't the only one assisting Harris in her preparation -- she's also enlisted former White House aides Karen Dunn, Sean Clegg and Rohini Kosoglu. All three worked with her during her 2020 vice presidential debate against Mike Pence.

Asked by reporters Wednesday how her debate preparations were going, Harris responded, "So far, so good."

While in Pittsburgh, Harris will work on maintaining a calm demeanor as she makes a case for her own presidency while holding Trump accountable for his, according to a source familiar with Harris' debate preparations.

If Trump dodges a question or begins launching attacks, she wants to be able to successfully pivot the conversation, the source added.

That same source said the vice president will also focus on avoiding going down policy rabbit holes, which the source said was something she did during her 2019 debates.

Harris' latest high-profile debates were during her presidential run four years ago and her vice presidential debate with Pence. This cycle, Trump debated President Joe Biden in June.

The ABC News debate will take place on Tuesday, Sept. 10 at 9 p.m ET. A prime-time pre-debate special will air at 8 p.m. ET.
