Donald Trump Jr., the president’s eldest son who helps run the Trump Organization as an executive vice president and has been one of his father’s most active surrogates this year, posted a photo of a “Don Jr. 2024” flag to instagram.

Donald Trump Jr. wrote that it will “make liberal heads explode” and that “to whomever made [the sign] thanks for the compliment… but let’s get through 2020 with a big win first.”

Eric Trump, also an executive vice president at the Trump Organization and a Trump campaign surrogate, liked a tweet on Saturday reading “Eric Trump 2024,” a move some commentators recognized as roughly equivalent to his brother’s instagram post.
