Even with a house vote it means nothing
Articles of impeachment as defined by the constitution is how impeachment is done.
Impeachment Inquiry is nowhere in the constitution
This is so their moderate members can say they did not vote for articles of impeachment. But the media will report that Trump was Inpeeched!
They are playing with words here
That's been my understanding and based on that fact, "impeachment inquiry" is nothing more than Pelosi trying to keep the AOC wing of the Democrat Party satisfied that something's being done about PDJT and gin up the media propaganda machine against the President.
Both will backfire bigly on her in short order.
