Taking a cue from his father’s playbook of using the social media platform Twitter to air his grievances with major mainstream media outlets, Donald Trump Jr. blasted the Washington Post over the estimated $10 million ad the paper ran during Sunday night’s Super Bowl.

The ad, which featured such iconic historical images as the D-Day invasion, the Selma civil rights protest, the American moon landing, the Oklahoma City Bombing, and George H.W. Bush’s funeral was followed by memorial tributes to journalists killed in the line of duty and classic lines such as “democracy dies in darkness” and “knowing keeps us free.”

The ad, despite its general non-political nature, was criticized by the eldest Trump son, who tweeted for following:

Trump Jr.’s slamming of the mainstream media comes on the heels of speculation (that has been reported by almost every mainstream media outlet) that an indictment is forthcoming.

In an interview with MSNBC’s Joy Reid on Saturday, former federal prosecutor Paul Butler discussed Special Counsel Robert Mueller’s probe into the alleged Russian election interference and similar matters.

Butler hypothesized that since Mueller is not likely to indict the president as the Department of Justice’s official stance is that no sitting president can be indicted, he will instead continue going after individuals in his inner circle. According to the former prosecutor, Mueller has “leverage” over President Trump because of the legal liabilities his son Donald Trump Jr. is facing.

“Mueller is not going to indict Trump, because he’s going to follow the DOJ employee handbook, but he has leverage over the president in terms of Donald Trump, Jr.,” Butler stated, adding that Trump Jr. “lied his butt off” when testifying before congress.

According to The Guardian, in November, Mueller obtained a guilty plea from Michael Cohen, one of Trump’s closest advisers for more than a decade, who admitted giving an untrue account to Congress about the Trump Organization’s effort to develop a tower in Moscow during 2016, pleading guilty to making a false statement, thus making him the first person prosecuted by Mueller over remarks to congressional investigators.

Following a guilty indictment of Roger Stone last month, many lawmakers and legal experts close to the Mueller investigation are hinting that others within the Trump Organization who have testified before the committee may have also lied and are therefore subject to indictment as well.

Whether or not Trump Jr. will be officially indicted remains to be seen, but one thing is for certain- the mainstream media will be there to cover it.
