House Speaker Nancy Pelosi has suggested that President Donald Trump is being blackmailed by Russian President Vladimir Putin in light of the indictment of Trump ally Roger Stone.

Early on Friday, Stone was arrested on a seven-count indictment for allegedly hindering special counsel Robert Mueller's investigation into alleged Russian election interference.

Prosecutors did not accuse Trump of wrongdoing in the indictment or charge Stone with conspiring with WikiLeaks or with the Russian intelligence officers Mueller says hacked emails damaging to Hillary Clinton's campaign. They also did not allege that Trump aides knew in advance of the hacking.

Pelosi said in a statement on Friday: 'The indictment of Roger Stone makes clear that there was a deliberate, coordinated attempt by top Trump campaign officials to influence the 2016 election and subvert the will of the American people.'

'It is staggering that the President has chosen to surround himself with people who violated the integrity of our democracy and lied to the FBI and Congress about it,' she continued.

Pelosi added that the indictments and Trump's vocal opposition of the Muller probe 'raise the questions: what does Putin have on the President, politically, personally or financially?'

Stone was arrested by the FBI in a raid before dawn Friday at his Florida home.

CNN, which claimed its producer was present based on a hunch, aired video of the raid at Stone's home in Fort Lauderdale, Florida, showing agents in body armor using large weapons and night-vision equipment, running up to the home and banging on the door.

'FBI open the door!' one shouts. 'FBI, warrant!' Stone could then be seen in the doorway in his sleepwear before he was led away.

Stone was released on a $250,000 surety bond hours later and swiftly blasted the prosecution as politically motivated.

In a circus-like atmosphere outside the courthouse, as supporters cheered him on and jeering spectators shouted 'Lock Him Up,' Stone proclaimed his innocence and predicted his vindication.

'As I have said previously, there is no circumstance whatsoever under which I will bear false witness against the president, nor will I make up lies to ease the pressure on myself,' Stone said.

Trump attorney Jay Sekulow said the indictment 'does not allege Russian collusion by Roger Stone or anyone else.'

Trump, in a tweet Saturday, said that if Stone 'was indicted for lying to Congress,' then 'what about the lying' by top law enforcement and Obama-era national security officials.
