Peter Dutton has leapt to the defence of Health Minister Greg Hunt, who has been accused of improperly interfering in the review of a medical product.
Mr Hunt has denied helping a Liberal Party donor push for a regulator's review a self-testing flu kit.
Emails obtained under freedom of information laws show the health minister's office was "very keen" for the Therapeutic Goods Administration (TGA) to review the devices.
The home affairs minister claimed the allegations levelled against Mr Hunt were "just false".
"I think we're being led in today's society by Twitter feeds from anonymous people - I think we need to strip that emotion away," Mr Dutton told the Nine Network on Friday.
"As I keep saying, let's stick to the facts."
The chairman of the company behind the medical devices has donated almost $600,000 to the Liberal and Liberal-National parties since 2014.
Labor's health spokesman Chris Bowen said the "unprecedented" ministerial intervention raised "huge concerns" about Mr Hunt's integrity.
"This blatant misuse and cover up of a respected independent process is the latest in a line of scandals from the Liberals and their mates," Mr Bowen said.
"Greg Hunt needs to stop misusing government processes and start taking action on the record high out of pocket costs and waiting lists in Australia's health system."
