SNL writer Katie Rich was inundated with complaints from Twitter users after she made a joke about ten-year-old Barron Trump on Inauguration Day

The White House put journalists on notice Tuesday that Barron Trump, the president's 10-year-old son, must be left out of political reporting.

The warning followed Saturday Night Live's decision to indefinitely suspend a staff writer who tweeted on Inauguration Day that the boy was destined to become 'this country's first homeschool shooter.'

The White House Press Office blasted out a message to reporters Tuesday afternoon, saying that '[i]t is a longstanding tradition that the children of Presidents are afforded the opportunity to grow up outside of the political spotlight.'

'The White House fully expects this tradition to continue. We appreciate your cooperation in this matter.'

Katie Rich, the SNL writer who made the bad-taste joke about Barron on Twitter – and deleted it three hours later – apologized for her 'inexcusable' actions after the show sidelined her from its joke-writing staff.

She apologized publicly on Monday for the 'insensitive' and 'inexcusable' joke. That same say it emerged that NBC had suspended her indefinitely for the bad-taste gag

Twitter users branded her 'scum', called for her account to be blocked, and urged NBC to fire her.

Rich deleted her entire Twitter history, replacing it with a since tweet reading: 'I sincerely apologize for the insensitive tweet. I deeply regret my actions & offensive words. It was inexcusable & I'm so sorry.'

Monica Lewinsky of Bill Clinton sex-scandal fame, not an anti-bullying activist, tweeted Saturday evening that 'all children need to be protected from bullying + mockery (incl #barrontrump). Let's be better than this.'

Rich was not credited on Saturday's edition of the show, and it's not known when she will return.

Many doubted the sincerity of her apology. Twitter user John McLemore suggested her 'conscience kicked in when the backlash started,' and Domenico Cusumano said: 'This came from somewhere that was contrived by the masses.'

Many responses to Rich's apology were angry; some doubted whether she was being honest, while others couldn't overcome their disgust at her initial remark

A user named 'Ashley' said: 'These people so quick to accept your insincere apology are the same ones that hold a grudge towards Trump for saying far less.'

Others were unable to overcome their disgust.

'Joey' complained: 'Attacking a 10 year old? Disgusting,' and Eric Mulholland wrote: 'Insensitive probably isn't the word for it. You should be fired for even thinking that was remotely funny.'

Rich did have some backers.

'We all make mistakes,' said Richard DeCosmis. 'Lets move on, and I'm a Trump supporter.'

'So many against your tweet preaching against insensitivity, but showing their own insensitivity in replies,' said Brad Leese. 'Hang in there!'

The SNL Afterparty podcast told Rich to 'write something great for next week's SNL'; it's not clear if this meant her 'indefinite' suspension will end soon

Some supported her only after she apologized, telling her to withstand the harsh criticism

Wenzier Power said: 'Love your work @katiemaryrich! It's sad that you're held to a higher standard than the President, but you're also clearly a bigger person.'

And a user named Margaret simply tweeted: 'tbh I lol'd. ¯\_(ツ)_/¯'

SNL's 'Afterparty' podcast tweeted: '[T]ake your lumps and then go write something great for next week's #SNL. #LifeGoesOn'

It's not clear whether that tweet indicates that Rich's 'indefinite' suspension will be over after this week.

Ten-year-old Barron, who was thrust into the limelight this weekend as he accompanied his family to Washington DC, will become the first son of a president to live in the White House since John F. Kennedy Jr.

But he will be staying put in New York with Melania Trump until he finishes out the year at the Columbia Grammar and Preparatory School, where tuition starts at $44,120 for those enrolling in pre-K.

Modern Family actress Julie Bowen made a series of posts Friday on Instagram targeting Barron Trump

Rich wasn't alone in incurring the wrath of Twitter users on Inauguration Day.

Modern Family actor Julie Bowen made a series of lighthearted posts expressing her dismay for the new president on her Instagram - making the mistake of sharing several screenshots of Barron taken during the inauguration.

Like Rich, she faced a barrage of comments that slammed her for singling out the boy, who was positioned behind his father.

Bowen posted a photo of Barron looking down and wrote: 'I think Barron is on his Gameboy. Can't say I can blame him.'

In another photo, showing the boy with both hands around his head looking bewildered, Bowen wrote: 'Barron, a voting majority shares your horror. #barronforpresident'
