Phil Griffin, president of MSNBC, says there’s something fishy about Tuesday’s ratings for the Fox News Channel, which were up significantly from a day earlier when Fox News debuted its new schedule. And he wants an investigation.

“Monday we had a really good day in the key demographic. On the night that Fox News debuted their three shows, we either tied or beat them in those hours,” Griffin said at a briefing, according to TVNewser.

“Tuesday — you guys should be doing some investigations; I have never seen it in all my years of cable — same overnight, same everything. And they doubled their ratings in a day? It is impossible.” Griffin continued, “I have never seen it. They did election-night numbers in the demo Tuesday.”
