Longtime Donald Trump confidante, Republican operative and serial hat-wearer Roger Stone claims he is the target of a sinister plot to silence him ahead of next week's Congressional investigations into the Russian hacking scandal.

Mr Stone made a series of sensational claims overnight after allegedly being involved in a hit-and-run on his way to Orlando to promote his latest book on the US President.

The controversial former Trump adviser told popular conspiracy theorist and Infowars host Alex Jones that his car was "T-boned" by "deep state" actors on Wednesday morning in an attempt to assassinate him before he could testify at the hearings, which start on Monday.

Longtime Donald Trump confidante, Republican operative and serial hat-wearer Roger Stone claims he is the target of a sinister plot to silence him ahead of next week's Congressional investigations into the Russian hacking scandal.

Mr Stone made a series of sensational claims overnight after allegedly being involved in a hit-and-run on his way to Orlando to promote his latest book on the US President.

The controversial former Trump adviser told popular conspiracy theorist and Infowars host Alex Jones that his car was "T-boned" by "deep state" actors on Wednesday morning in an attempt to assassinate him before he could testify at the hearings, which start on Monday.

"They have poisoned me, they have smeared me, and someone in a car tried to kill me," Mr Stone told Jones via satellite during an appearance on the show shortly after the incident.

"I am a consistent critic of the 'deep state'— that's why I think I'm targeted."

The term "deep state" derives from the Turkish derin devlet which refers to a secret network of intelligence and military officers who worked with civilian allies to preserve the secular order established in 1923 by post-Ottoman Turkey.

In the US, "deep state" is viewed by many as a conspiracy theory alluding to a clandestine coalition of security forces (CIA, FBI), influential financial institutions and identities (like George Soros) and more recently, Obama administration figures, working together to undermine President Trump.
