Donald Trump Jr. questioned the military service of Lt. Col. Alexander Vindman, and was sprayed with venom.
The president's eldest son posted a link to a Federalist article suggesting Vindman is not a dedicated military officer and public servant, a line of questioning which Rep. Jim Jordan (R-OH) also pursued during an impeachment hearing.
"Let’s Stop Pretending Every Impeachment Witness Is A Selfless Hero," Trump Jr. tweeted, quoting the piece's headline.
His suggestion infuriated other social media users.
