David Shuster Resurfaces

David Shuster has resurfaced — on Twitter, at least.

The MSNBC anchor, who had been silent on Twitter since January and off-air since April, popped up Thursday to thank followers for their birthday wishes.

"Thanks everybody. And a special thanks on this day to @joenbc," Shuster tweeted, referencing MSNBC colleague Joe Scarborough, who had tweeted him a happy birthday earlier in the day.

Shuster was silenced on Twitter in January, muzzled by MSNBC following a controversial tweet to conservative activist/journalist James O'Keefe. After reportedly filming a pilot for CNN, he was suspended indefinitely by the network in April. He has not been back on the air since. MSNBC President Phil Griffin said Shuster was "not moral, ethical, or professional" in his actions.
