This is the first lady’s first effort for Harris since giving a brief endorsement at the Democratic National Convention in August.

Beginning Friday, Biden is slated to visit Arizona, Nevada, Wisconsin, Michigan, and Pennsylvania across five days, according to CNN. Biden hasn’t been campaigning since her husband, President Joe Biden, dropped out of the race in July.

The Washington Examiner reached out to the Harris campaign for comment.

As first lady, Biden has increasingly stepped into a formal role. In September, she sat at the head of the table during a Cabinet meeting and followed up with a Rose Garden event without her husband present at all. The president has largely stayed out of the public eye since he ended his campaign in July.

Jill Biden has released three children’s books since 2012, including Willow The White House Cat, Don’t Forget, God Bless Our Troops, and Joey: The Story of Joe Biden. She continues to work as an English professor at Northern Virginia Community College.

Gov. Tim Walz (D-MN), Harris’s running mate, will also be touring states for rallies, direct voter engagement events, fundraisers, and two national TV interviews.
