The presumptive Democratic presidential nominee was speaking to reporters as she bought a cold tea at Uprising Muffin Company in Washington, D.C.'s Shaw neighborhood Friday.

“Have you talked about vice presidential possibilities with Sen. Warren?” one reporter is heard asking in a video tweeted by CBS reporter Hannah Chanpong.

The presumptive Democratic nominee exaggeratedly bobs her head, widens her eyes and then laughs when a few reporters repeat the question. 

“You guys have got to try the cold chai,” Clinton responded, holding up her tea.

Warren met privately with Clinton on Friday morning amid increasing speculation that Clinton will tap her to be her running mate.

The meeting came just one day after Warren formally endorsed Clinton for president.
