Interim chair of the Democratic National Committee (DNC) Donna Brazile on Saturday said the Democratic Party got "cocky" during the 2016 election.

"I'm not going to sugarcoat it: We failed,” Brazile said during her speech at a DNC event in Phoenix, according to The Washington Post.

"We made some serious mistakes and some strategic errors. We got cocky about our invincible blue wall, and then we saw it crumble because of just a few thousand votes in Pennsylvania, Michigan and Wisconsin."

Brazile argued that Russian hackers enlisted American media for its own ends, according to the Post.

“We failed under extraordinary circumstances,” she said. “If you are an American, you are a victim of a hostile attack, a murderous dictator who wanted to affect the election. They hired an army of trolls to spread lies and distract from the real issues.”
