Transportation Secretary Pete Buttigieg has cancelled an item on his upcoming schedule amid reports he may be in the running to be Kamala Harris' vice president.

Pennsylvania Gov. Josh Shapiro -- also among the VP hopefuls -- canceled fundraisers he had planned for the weekend.

Buttigieg, who has been traversing the Midwest this week in his official capacity, is scheduled to on Friday tour Ivy Tech Community College in Kokomo, Indiana. After remarks, the secretary will have a media availability.

"Secretary Buttigieg is here in Kokomo in his official capacity as Transportation Secretary. Federal law prohibits him from speaking about campaigns and elections," his team wrote in email guidance.

He was slated to hold a roundtable discussion afterwards, which his team now says will no longer happen.

"I’m sorry to share that we will no longer be hosting the roadway safety roundtable due to some unforeseen scheduling constraints," the guidance reads.

Pennsylvania Gov. Josh Shapiro -- who is reported to have met with Harris' vetting team as he remains on the shortlist of her vice presidential options -- has canceled the fundraisers he had planned in the Hamptons this weekend, ABC News has confirmed.

It's unclear now what his weekend schedule entails.

"The Governor's trip was planned several weeks ago and included several fundraisers for his own campaign committee. His schedule has changed and he is no longer traveling to the Hamptons this weekend," Shapiro Spokesman Manuel Bonder told ABC News.
