Many attempts, few successes: Impeaching the US president - Standard Chartered
"The US Constitution allows any member of the House of Representatives to submit an impeachment resolution against the president if there is a suspicion of treason, bribery, or other crimes and misdemeanours," Standard Chartered analysts point out.
Key quotes
"But while initiating impeachment proceedings may appear fairly easy, the process needs to clear various technical and political hurdles. Resolutions to initiate impeachment proceedings have been made against 13 presidents, but only two have led to impeachment (by the House) and none have led to conviction and removal from office (by the Senate)."
"Ultimately, full impeachment proceedings culminating in the president’s removal from office would be a political rather than a legal decision. Even if the Democrats gain ground in the November midterm elections, this is unlikely to result in a Senate supermajority ready to convict Trump, in our view."
