I watched the ENTIRE segment. 

Acosta came across as rude and boorish. He would pretend to ask a question but it was clear from his interrupting he didn't care about the answer.  I was actually interested in the answers, but didn't get to hear most of them due to his MANY interruptions. It's also obvious now that Acosta's grandstanding and speech-making instead of asking questions and hearing the answers is why Spicer stopped the video recording of press briefings for a while. 

Acosta is clearly there to hear himself talk. They need to have a separate briefing without him so everyone else can actually hear the briefing.
