Howard Stern's engineer of more than 30 years/on-air personality Scott 'The Engineer' Salem has reached out to the public asking for $50,000 via a GoFundMe drive for his wife's battle with cancer, leading some to question if the wealthy radio personality has chipped in to help.

Salem, 64, posted a link to the fundraiser on Sunday in an effort to help his wife Robin in her five-year battle against colon cancer and lymphoma, which she has bravely fought through a gauntlet of chemotherapy treatments, surgeries and debilitating side effects.

The condition has left Robin bedridden for the better part of two years - as her lymphoma recently resurfaced after a period of remission - but 'Robin is a fighter' and 'will never give up,' according to Salem.

Time in need: Howard Stern's engineer of more than 30 years/on-air personality Scott 'The Engineer' Salem (R) has taken to Go Fund Me to raise money for his wife Robin's ongoing battle with cancer

Salem said his family has faced significant financial challenges dealing with costs not covered by their insurance, such as nursing care, medical equipment and home modifications to accommodate Robin's needs.

'We have drained our savings and have gone into considerable debt to cover the related expenses,' Salem wrote. 'We ask you to please donate whatever you can, $1, $5, $10, any amount will help Robin continue her fight against this devastating disease.'

The plea garnered an immediate response, as the campaign had amassed more than $41,000 from nearly 1,400 donors to help the family in their time of need as of late Tuesday.

The campaign also caught the attention of former Stern co-host Artie Lange, who confirmed via Twitter he's 'helped a bit' and is 'committed to more,' calling Scott 'a great guy' and Robin 'one of the sweetest souls I’ve ever met.'

Successful: As of Tuesday, the campaign had drummed up more than 80 percent of its $50,000 goal, with some questioning if Stern had contributed to that tally

Amid the warm sentiment, some wondered why Howard, 64, had stayed silent on Salem's fundraiser both on social media or his SiriusXM program Monday or Tuesday.

Though it was not immediately clear if the Private Parts star had donated to the cause, numerous sources said that Stern - who made $90 million last year to claim the seventh spot on Forbes highest-paid celebrities list - had not contributed. (Dailymail.com has reached out to both Stern and Salem for comment on this story, but has not heard back as of Tuesday evening.)

One reason could be a lack of communication, former Stern Show personality 'Stuttering' John Melendez said, relaying an anecdote illustrating how Stern has kept his staff at an arm's length in recent years - including Salem, whose work alongside the King of All Media dates back to 1986.

'I heard a story where Scott the Engineer went up to Howard and approached him, and Howard told him, "You know you're not allowed to talk to me,"' Melendez said on The Stuttering John Podcast, citing multiple sources who continue to work alongside Stern and Salem on the radio show. 'I mean, Scott the Engineer, the guy's been there for 50 years.'

Melendez called it 'pathetic' that Stern 'didn't help' Salem in a podcast Tuesday.

'Howard, come on man, this is ridiculous - how has Scott, a man who's worked for you for 30 years, set up a Go Fund Me campaign?' said Melendez, who left Stern in 2004 to work on The Tonight Show with Jay Leno. 'I mean, come on ... how many millions do you need, Howard? At this point, how many billions do you need? You got three f***ing mansions!'

Melendez, who appeared on Stern's show for 14 years, continued, 'It's so sad that Scott Salem - a fixture on the show - that he has to go out and ask people for money is just a travesty. And Howard, really, you should be ashamed of yourself.

'Scott has been there for you since day one, he was a soldier of yours - be there for him!'

Critics: Both Gregg 'Opie' Hughes and 'Stuttering' John Melendez have taken Stern to task, with both claiming Stern has NOT contributed to the charity push for his longtime engineer

Also critical of Stern was radio personality Gregg 'Opie' Hughes, a one-time radio rival of Stern who hosted a show at SiriusXM for nearly 10 years until leaving the company in 2017.

'Not only has he done nothing to help him as of yet, nor mention on the show, which would bring in tons of money ... but I hear Scott went in for a raise [because] this has been going on for some time, and he did not get one,' Opie told Dailymail.com, citing sources who still work at the satellite radio behemoth.

'Last week they mocked him MERCILESSLY and the whole staff was laughing, knowing fully well his wife was so ill, it made us sick!' he said.

Opie said he was compelled to donate as well as tweet a link for Salem's campaign to his sizable Twitter audience of 357,000 followers.

Referencing Stern and wife Beth's well-publicized fostering of kittens, Opie added, 'Howard cares way more about cats than people.'

The reception was equally as chilly amid a number of fan forums such as Radio Gunk and Reddit, where many users seemed aghast at Stern's lack of response or outreach to the heartbreaking situation.

'If I had a tenth of [Howard's] money and an employee of mine who worked for me for as long as Scott ... I would offer to pay for his wife's medical bills as a thank you for his years of service to help me put on a great radio show,' a Reddit user under the handle RelentlessGrind wrote. 'At the very least I would throw my weight around with Sirius executives and have the company pay the medical bills in full.'

On Radio Gunk, a regular listener named Benjamen took things a step further, saying that Salem - mocked for decades on the show for his bad luck - became grist for Stern's mill because of the tragic circumstances he faced at home.

'The Stern crew suddenly reintroduced us to Scott last summer, after years of absence from the show,' Benjamen wrote. 'All Howard wanted to hear about was how miserable Scott's life was, knowing exactly what was going on. They tiptoed around it using vague language, leaving most of us speculating divorce because of some of Howard's comments.'

He noted how a recurring bit on the show centered around Salem's debt to another staffer over a ticket to a baseball game.

'Everyone piled on with their miserable cheapskate Scott mockery, and then the Stern crew does what they always do: Beat to death anything that receives any positive reaction,' Benjamen wrote. 'Every week since then we've heard countless bits and songs about how depressed Scott is, sung by Scott himself.

'All this time they've known about the real misery: Scott's wife has cancer, and they've wiped out their life savings to battle it. And they have this man sing song parodies about how mopey he is?

'I ask this all the time: Are we listening to the worst human beings ever to walk the earth?'
