(CNN) – After offering presumptive GOP nominee Mitt Romney the advice to "hire some real pros" Sunday, Rupert Murdoch followed up Monday, saying he was still in Romney's camp – and that he's been taking some heat over his original tweet.
On Sunday, Murdoch's campaign recommendation was candid:
The message wasn't the first time Murdoch has used Twitter to offer sharp criticism of Romney. Last week he slammed the former Massachusetts governor and two-time presidential candidate for his immigration position.
On Monday, Romney's campaign strategist Eric Fehrnstrom responded to Murdoch's tweets on MSNBC.
"We're happy with the team that we have," Fehrnstrom said. "We're happy with the state of the race. I can't respond to every tweet that Mr. Murdoch sends out, but we like the way things are."
Murdoch's conglomerate, News Corp., owns media properties across the globe, including the Wall Street Journal and Fox News Channel in the United States. In Britain, his newspaper empire includes The Sun and the Sunday Times. In 2011 and 2012, Murdoch has been embroiled in a scandal involving alleged phone hacking at some of his newspaper holdings.
While some of Murdoch's media titles - including Fox News and the New York Post - carry known conservative leanings editorially, the man himself has been known to support candidates of both parties. In 2006, he was reported to have held a fund-raiser for then-Sen. Hillary Clinton, a Democrat, and in 2008, he called then-candidate Barack Obama a "rock star" and praised his education plan. In 2010, News Corp. gave a $1 million donation to the Republican Governors Association.
Murdoch, a native of Australia and a naturalized American citizen, is a regular tweeter, sending several messages per week and responding to his followers when they write to him with questions.
Aside from his candid thoughts on Romney, Murdoch also weighed in on this week's bombshell celebrity headline.
"Scientology back in news. Very weird cult, but big, big money involved with Tom Cruise either number two or three in hierarchy," Murdoch wrote.
