Over the July 4, 2016 weekend, controversy arose when Trump's Twitter account posted an image selected by Scavino of Hillary Clinton with a text in the shape of a Star of David calling her the "Most Corrupt Candidate Ever."

[9] On December 22, 2016, Scavino was named White House Director of Social Media under President Donald Trump.

[17] On June 18, 2019, USA Today released an article stating that Scavino was the writer of several of Trump's tweets, most likely those sent between 10 a.m. and 6 p.m. and those without spelling mistakes.

[20] In December 2020, after Trump lost the election, standing in a hallway near the Blue Room of the White House, Scavino told Jenna Ellis that Trump would refuse to leave office, as Ellis told Georgia prosecutors nearly three years later when she pleaded guilty in the Georgia election racketeering prosecution.

"[22] On September 24, 2021, the U.S. House select committee investigating the January 6, 2021 Capitol attack subpoenaed Scavino for records and testimony.

[25][26][27] On April 6, 2022, the House voted to hold Scavino and Peter Navarro in contempt for refusing to testify before the committee.

[30] On November 13, 2024, Trump announced Scavino would serve as principal White House deputy chief of staff in his second term.
