These are the four different types of investigations looking at Donald Trump
US President Donald Trump is facing so many investigations it can be hard to keep track.
Federal, state and congressional forces are looking into every corner of his personal, political and business life, generating so much news that one probe can blur into the next.
The special counsel investigation
If you follow US politics, or even if you don't, you've probably heard about Robert Mueller's investigation (AKA the Russia Probe.)
The former FBI director was tasked with investigating "any links and/or coordination between the Russian government and individuals associated with the campaign of President Donald Trump."
Mr Mueller, who has broad powers to interview witnesses, issue subpoenas and work with the FBI, has been running his investigation for more than two years.
So far, he's snared three companies and 34 people including Mr Trump's former national security advisor Michael Flynn, his former campaign chairman Paul Manafort and his former confidant Roger Stone.
Despite plenty of whispers, it's unknown how much longer the probe will continue.
