When Sen. Cory Booker (D-N.J.) lashed out against Homeland Security Secretary Kirstjen Nielsen this week, he became the latest potential 2020 presidential candidate to use a high-profile Senate committee hearing to amplify their stature. 

Booker mostly got what he wanted: his fiery questioning of Nielsen at a Senate Judiciary Committee hearing on Tuesday played on loop across the cable networks and fired up the conversation around his would-be candidacy [.....]

I watched it, it was an incredibly eloquent and skillful take down of Nielsen with just the right precise smidgen of outrage and emotion, not too much. Because it was so skillful, I think this is why GOP media reacted so strongly against it. I recommend others seek it out.  Note that at the end,there's a sort of wink when Booker graciously thanks  Sen. Graham, as chairman of the committee, for the opportunity to join it, and Graham basically responds in a way to say you're welcome, I mean really really welcome, this could be good....
