Former Secretary of State Hillary Clinton and Rep. Alexandria Ocasio-Cortez (D-N.Y) joked Thursday about White House senior adviser Jared Kushner's alleged use of WhatsApp for official business.

Ocasio-Cortez mimicked a popular joke about 2016 presidential campaign controversy over Clinton's private email use while at State, saying "But his WhatsApp" when sharing Rep. Ro Khanna's (D-Calif.) interview on CNN about the Kushner allegations.

Clinton responded to Ocasio-Cortez's tweet saying "Tell me about it."

The House Oversight and Reform Committee obtained information Thursday showing that Kushner, who is also President Trump's son-in-law, used WhatsApp and his personal email to conduct official government business.

During the 2016 presidential election, then-candidate Trump would frequently criticize Clinton, his Democratic opponent, for using a private email server while secretary of State.
