I agree so much. They should arrest and imprison Merrick Garland for contempt of congress. Then, if the Director of the FBI does not comply, arrest and imprison him. And then, if the next guy down the chain does not comply, arrest and imprison them. And so on down the line. If the last step proliferates into a group or a team, arrest and imprison the whole group if they or someone in it does not comply. If no one has turned over the evidence at this point, make it known that they will stay in prison until Congress gets the evidence. Make it known to the families that this could continue through multiple sittings of Congress. And stop their salaries. Also declare their pensions void, unless they comply. Anyone complying will unlock the bars for everyone. If this doesn't rat out the weak link, I don't know what will.

It's a dream, but it should be a satisfying dream to have it at all.

Or impeach the sitting President for failing to observe his duty. I know this gets laughable, when considering the present crowd, but in so many things, the Deep State relies on the inertia and lassitude of an indecisive Congress.
