(WASHINGTON POST) — Supporters of Mitt Romney are pushing back against calls for a campaign shake-up from Rupert Murdoch and Jack Welch, two industry titans who recently took to Twitter to advise the Republican presidential candidate to dump his staff.

Murdoch was among 50 people who met with the former Massachusetts governor at the Union League Club in New York City on Thursday afternoon.

Murdoch, the chief executive of News Corp., which publishes the Wall Street Journal and operates Fox News Channel, tweeted Sunday that Romney’s campaign team is insular and outmatched by President Obama’s.
