President-elect Trump chastised Hillary Clinton campaign chairman John Podesta and Democrats for being careless with their cybersecurity after WikiLeaks founder Julian Assange claimed a 14-year-old could have hacked their email systems.

“Julian Assange said ‘a 14 year old could have hacked Podesta,'” Trump tweeted. “Why was the DNC so careless? Also said it wasn’t the Russians who gave info!”
