Michael Flynn's son blames hacker after his disgraced father posts a cryptic tweet

Disgraced former National Security Advisor Michael Flynn on Friday tweeted and then quickly deleted an unusual message on Twitter.

The photo shows Hillary Clinton, sitting with disgraced Hollywood mogul Harvey Weinstein and her longtime aide Huma Abedin. The tweet was his first since December, according to his timeline.

Flynn pleaded guilty in 2017 to lying to the FBI about his conversations with the Russian ambassador.

His son, Flynn Jr., claimed that his father's Twitter account had been hacked.
