You don't get it. If people are fired for their age, there is no proof that was the reason. So the people that were fired have no recourse. Many thousands of gray haired old people are fired/ cut/ let go/ forced to retire every year. Many reasons can be given to mask the real reason - age. You must be young and have not worked long. Keep your eyes open. Over time you will see what I mean.
Bullshit. For every millennial that is age discriminated against, there are 10,000 boomers with gray hair that get sent packing because of their [old] age. No lawyers are involved 99.999% of the time.
Uhm no, an impeachment trial and a vote has to happen in the Senate. That will not happen during Trump's state of the union address. That process will take many months.
