He was impeached... twice! (Only president ever)
No
For the first impeachment it was only recommended and then acquitted.
For the second the articles of impeachment were drawn but also acquitted.
Sorry you dont get to make up your own definition. He was impeached twice. These decisions cannot be undone or removed or acquitted, he is officially formally and forever impeached. Being impeached means being tried for crimes. He was completely tried, and therefore completely impeached. Only president to get impeached twice. And only three presidents have ever been impeached at all. Super embarassing that he is president again.
"If the House adopts the articles by a simple majority vote, the official has been impeached."
