"Treason against the United States, shall consist only in levying War against them, or in adhering to their Enemies, giving them Aid and Comfort."
It is very annoying when people talk about "treason" or "impeachment" simply because they disagree with what an elected official has done. Treason consists of waging war against the U.S. or, in time of war, giving aid and comfort to the enemy. And that is in a direct and literal sense, not like saying, "it helps our enemies to pit us deeper into debt or shut down the government," or whatever.
Impeachment and removal of office is applicable to the commission of a crime. Again, not because you think the official is "a Marxist" who is ruining the country and not even because they lied (unless under oath). For example, the political left called for the impeachment of George W. Bush because they claimed he "lied" about weapons in Iraq both to the Congress and the whole country in the State of the Union Address. Well, guess what, even if that were true, it is not a crime. It would not have been an impeachable offense.
Time to stop throwing around these very specific legal terms. If you don't like the people in office, vote them out, but don't yammer on about impeaching them or about how they have committed treason. Such talk is just ridiculous.
