>To be impeached, a President or other federal official must have committed one of the violations described by the Constitution as “treason, bribery, or other high crimes and misdemeanors.” But history shows that if a President is to be impeached, the biggest factor may be political will — whether members of a President’s own party are willing to turn against him, and whether enough members of Congress believe that trying to remove the President is worth the risk of losing popular support.

>To impeach an official, the House of Representatives must pass articles of impeachment, which formally accuse the President of misbehavior. Once the House votes to impeach, the Senate must hold a trial to decide if the President should be removed from office.

So no, Trump (nor Clinton nor Johnson for that matter) was/were not impeached. They were all acquitted of the charges presented and even foregoing that the Senate ultimately lacked the political will to impeach them.

They were all tried for impeachment but they were not "impeached". To be impeached means they were found guilty of the charges (article(s) of impeachment) levied. It's like calling someone acquitted of murder a murderer, that's not how this works at all.
