The FBI began an investigation to determine whether US President Donald Trump worked "secretly" for Russia, after the president fired the then director of that intelligence body, James Comey, reported this Friday the newspaper The New York Times.
According to the New York newspaper, which anonymously quotes former FBI officials and other sources close to the alleged investigation, the top intelligence agency was "worried" about Trump's behavior after Comey was dismissed.
"They were so concerned about the behavior of the president that they began to investigate whether he had been working on behalf of Russia against US interests", the newspaper said.
Investigators had to consider whether Trump's actions constituted a possible threat to US national security and they tried to determine if the president was knowingly working for Moscow or if, unknowingly, he had fallen under its influence.
That FBI investigation also examined whether Trump committed obstruction of justice with the dismissal of Comey, given that the president linked the official with the investigation of the so-called "Russian plot".
The special prosecutor Robert Mueller investigates since May 2017, independently from the Government, the possible links between members of the Trump campaign and the Kremlin, which the intelligence agencies accuse of interfering in the 2016 election in favor of the Republican candidate, in addition to the supposed crime of obstruction of justice.
According to the Times, Trump called the attention of the FBI when he asked Russia to pirate the emails of the Democratic candidate to be US president, Hillary Clinton, during a press conference in the election campaign.
Likewise, Trump refused to criticize Moscow during the election campaign and has repeatedly praised Russian President Vladimir Putin, theoretically antagonistic to the interests of the North American country.
The Times sources argued that the FBI's concern grew when the British ex-spy Christopher Steele gathered compromising information about Trump which claimed that Russian intelligence had contacted him with the aim of blackmailing him in the future and gaining his support in various foreign policy matters.
