Mueller has to hurry, and bring the Obstruction of Justice case before Congress.

With Trump, things are so volatile and chaotic, things could become really bad, really quickly.

Trump's sloganeering is being virtually ignored.  No one believes him anymore.  So, the economy follows suit.

Add in the obvious fumbling with international issues, the new partnership that is coalescing between China and Russia AGAINST the US over NK (and their eventual increased power in the region), as well as Trump's foolish big body promises of, and forays into additional military engagements, and the bottom could drop out quickly.

Then, add in the effects of the Hurricane season on the Gulf and East Coasts.

Congress needs to be armed NOW, with tools and justifications necessary to impeach Trump quickly.

Things are turning.  You can see, feel, read about, and hear about it clearly.  Trump's bombast can't settle markets, scare other nations, or lead Americans.  There's no respect for him.
