Special counsel Robert Mueller's probe into possible ties between President Donald Trump's campaign and Russia has picked up steam. DW takes a look at the recent developments.
What's the scope of the special counsel investigation?
Robert Mueller is authorized to investigate "any links and/or coordination between the Russian government and individuals associated with the campaign of President Donald Trump."
Mueller's remit also allows him to potentially broaden the scope of the probe and look into "any matters that arose or may arise directly from the investigation."
Mueller's jurisdiction as special counsel also authorizes him to "investigate and prosecute federal crimes committed in the course of, and with intent to interfere with, the special counsel's investigation, such as perjury, obstruction of justice, destruction of evidence, and intimidation of witnesses."
What powers does a special counsel have?
Essentially, a special counsel has the same powers as a regular federal prosecutor, with the difference being that he or she operates outside of the normal Justice Department hierarchy. Special counsels have their own budget, can hire their own staff, and investigate, subpoena and prosecute individuals.
Mueller has aggressively pursued criminal charges against people who have lied during the Russia investigation. So far, Mueller has charged at least six people with crimes involving making false statements to Congress, the Justice Department or the FBI. They include Trump's former lawyer Michael Cohen, who was sentenced to three years in prison in December on charges involving campaign finance violations, tax evasion, and lying to Congress about plans to build a Trump Tower in Moscow during the 2016 presidential campaign.
How dangerous is this for Trump himself?
It's widely believed that Mueller won't actually indict Trump, thereby adhering to the Justice Department's view that the Constitution bars the prosecution of sitting presidents.
According to the president's legal team, Mueller has indicated that he is writing a report on Trump's conduct, similar to independent counsel Ken Starr's investigative account of former President Bill Clinton in 1998.
Beyond that, it could kick-start a debate over impeachment in the newly Democratic House of Representatives.
