A closer look at the US impeachment process and how it works

Impeachment is the mechanism by which a sitting US president can be removed from office for high crimes and misdemeanours.

The US Congress is made up of two chambers - the 435-member House of Representatives which votes in the first stage of impeachment proceedings and the 100-seat senate.

For Donald Trump to be removed from the White House, two-thirds of senators would have to find him guilty.
