Chris Hayes hilariously trolls Trump and Sean Spicer for 'huge' boost president gave to book sales

Former press secretary Sean Spicer is trying to cash in on his time at the White House working for President Donald Trump. It isn't quite working out as well as planned, however.

The president tried to help give a boost to his former staffer, and he certainly succeeded, though not by much. On Saturday President Trump tweeted: "A friend of mine and a man who has truly seen politics and life as few others ever will, Sean Spicer, has written a great new book, “The Briefing: Politics, the Press and the President.” It is a story told with both heart and knowledge. Really good, go get it!"

The nearly 15,000 likes the tweet received did not translate well into book sales.

"President Trump might not be much for book reading, but he's happy to plug books by people who have remained loyal and haven't spilled anything juicy about their six-month stint at the white house," said MSNBC's Chris Hayes.

"If you take a look at data from novel rank from sites that Amazon book sales you'll see a big jump on Saturday the day Trump tweeted about the more than a 130 percent increase in fact," Hayes said.

An 130 percent increase can be misleading, so Hayes broke down the math.

He continued: "Except the grand total was, drum roll, please, 14 copies sold. Now, that is up from 6 the day before. Now, to be fair, that does not include e-book sales, and Spicer did rack up nine of those on Saturday and then another eight on Sunday. It is not immediately known whether the president was one of those pre-orders.
