The Rachel Maddow Show, in particular, has devoted a lot of time on the Mueller investigation. "MSNBC's Rachel Maddow, like many of her contemporaries, has found that the era of President Donald Trump is, if nothing else, great for business," says Tim Marcin. "Maddow's rating surge, though, came in concert with a unique drawn-out style and a particularly dogged focus on Trump's potential connections to Russia and the various investigations into the leader of the free world. But could the very strategy that helped propel her to the top of the ratings now be in jeopardy?" ALSO: President Trump boasts CNN and MSNBC's ratings have "tanked" due to Mueller's findings, while Fox News is up "BIG."
