President Donald Trump takes office in circumstances unlike any in US history. He assumes executive authority, and his nuclear launch codes are being activated at a time when there is reported to be a broad, multi-agency investigation into possible collusion between the Kremlin and officials on his campaign. US intelligence agencies have already concluded that Vladimir Putin interfered in the presidential election in Trump’s favour. The night before his inauguration, the New York Times quoted current and former senior US officials as saying that law enforcement and intelligence agencies were examining intercepted communications and financial transactions as part of their inquiries. On Wednesday, the McClatchy news agency reported that the FBI and five other agencies had been collaborating for months in an investigation into the extent of Russian attempts to skew the election. The report said that investigators were examining how money may have been transferred by the Kremlin in its covert bid to help Trump win. One possibility was that a system used to pay Russian-American pensioners was used to pay email hackers in the US. Once Trump takes the reins of power, however, he has the authority to stop all executive branch investigations.
He could replace the FBI director, James Comey, although it is highly unusual for a FBI chief to be fired before the end of his 10-year term. Bill Clinton sacked director William Sessions in 1993, on the basis of an investigation into his conduct carried out under George HW Bush into alleged abuse of office. However, barring evidence of blatant wrongdoing by Comey, any move by Trump to dismiss him while the president’s associates were under investigation would be highly controversial, akin to Richard Nixon’s dismissal of special prosecutor Archibald Cox in 1973.
Congress has also launched its own investigations. The Senate intelligence committee announced last week that it planned to interview senior figures in the incoming administration as part of its inquiry into Russian hacking of the election, and a subcommittee of the armed services committee, run by Trump’s Republican nemesis, Senator John McCain, is pursuing a parallel enquiry.
On 9 December, McCain personally handed Comey a set of reports alleging the Trump campaign’s collusion with Moscow, compiled by former MI6 officer Christopher Steele, as part of opposition research conducted by the campaign, although the FBI had first received the reports months earlier.
