California Gov. Gavin Newsom (D) trolled Vice President JD Vance over his reported attendance at a White House peace summit on Ukraine, appearing to mock Vance’s role as the president’s attack dog.

In recent months, the governor has adopted an aggressive social media strategy as he’s become one of the most prominent Democratic Party critics of the Trump administration.

Newsom, seen by many as a potential presidential candidate in 2028, and his press team have taken to mimicking Trump’s social media writing style, in particular the all-caps screeds and nicknames that have become familiar tropes.

They have now turned their attention to Vance, who is also seen as a presidential hopeful for the next general election.

On Monday, the Democrat responded to reports that Vance would be in the Oval Office when Trump meets Ukrainian President Volodymyr Zelenskyy later in the day.
