We at Twitchy enjoy the tweets of CBS News’ Mark Knoller for two reasons in particular. First, Knoller knows his stats; the Washingtonian named him “the unofficial records keeper of the presidency, the statistics savant of 1600 Pennsylvania Avenue.” Ask him how many times Obama has played golf during his term, and Knoller will answer — leading to cries of partisan bias and reminders that George W. Bush golfed too.

Second, Knoller is a master of subtle snark: just check out this tweet about Thursday night’s DNC fundraiser at a private home.

Of course the press isn’t allowed. Even ABC’s former White House correspondent, Ann Compton, told members of the White House Correspondents’ Association recently that “it’s as if we were all carrying the Ebola virus” when it comes to gaining access to the Obama administration.
