For more than a year, President Donald Trump has insisted that Russians did not interfere in the 2016 election, going so far as to call such allegations a “hoax” and a “made-up story.”

On Friday, special counsel Robert Mueller, the man charged with investigating the Trump team, filed indictments filled with cold, hard fact, charging 13 Russian nationals with executing an incredibly sophisticated cyber-based operation to aid Trump’s bid for the presidency.

In other words, Mueller called Trump’s bluff.

The defendants “engaged in operations primarily intended to communicate derogatory information about Hillary Clinton, to denigrate other candidates such as [Sen.] Ted Cruz [R-Texas] and [Sen.] Marco Rubio [R-Fla.], and to support Bernie Sanders and then-candidate Donald Trump,” Mueller wrote.
