Don't call into question the patriotism of a Purple Heart recipient and expect to walk away unscathed.

On Thursday, Sen. Marsha Blackburn (R-Tenn.) tweeted several inflammatory things about Lt. Col. Alexander Vindman, the director of European Affairs for the White House National Security Council. Vindman was on President Trump's July 25 phone call with Ukrainian President Volodymyr Zelensky, and while testifying before House impeachment investigators, Vindman said he was troubled by Trump's request that Ukraine open an investigation into former Vice President Joe Biden, and knew he had to inform superiors.

During the afternoon's impeachment proceedings, Rep. Adam Schiff (D-Calif.) called Vindman an "American patriot," which led to Blackburn tweeting, "How patriotic is it to badmouth and ridicule our great nation in front of Russia, America's greatest enemy?"

Vindman's lawyer David Pressman reacted swiftly, saying in a statement, "This difficult moment in our country calls for seriousness and seriousness of purpose. Lt. Col. Alexander Vindman has sacrificed enormously for our country. He believes in our country. And he believes in our country's great institutions, including the United States Senate." Vindman served in the Iraq War, and received a Purple Heart for injuries he sustained in an IED attack.

"That a member of the Senate — at a moment when the Senate is undertaking its most solemn responsibility — would choose to take to Twitter to spread slander about a member of the military is testament to cowardice," Pressman continued. "While Sen. Blackburn fires off defamatory tweets, Lt. Col. Vindman will continue to do what he has always done: serve our country dutifully and with honor."
