A comedy writer claims that President Donald Trump blocked her on Twitter after she made a joke about his tweets about health care.

Bess Kalb, an Emmy-nominated Jimmy Kimmel Live writer, has regularly replied to Trump's tweets with jokes over the last several months, but it appears the president thinks she's taken it too far.

'OH. MY. EFFING. GOD. The president of the United States just blocked me on Twitter because I hurt his feelings. #MAGA,' she wrote on Twitter, attaching an image of Trump's blocked page.

Jimmy Kimmel Live writer Bess Kalb has regularly replied to President Donald Trump’s tweets with jokes over the last several months, and now says that she was blocked by the Commander in Chief on Sunday

She later added in a follow up, saying: 'From now on, there is only one Snowflake.'

'It is mortifying, yet unsurprising to me that the leader of the free world could be so wounded by the gentle ribbing of a comedy writer,' she said.

'And if I could talk to him now I'd tell him: "Donald, sticks and stones may break your bones but articles of impeachment will harm you,"' she added.

'And honestly, he just lost my vote,' she joked.

The tweets she believed she was blocked for came after Trump tweeted on Sunday: 'I suggest that we add more dollars to Healthcare and make it the best anywhere. ObamaCare is dead - the Republicans will do much better!'

Kalb, who also writes for the New Yorker, responded to the tweet: 'Oh boy, honey. I've tried to lay off and let you be President like you said you would, but this is a new kind of simplistic rhetoric.

'I know you're trying to pivot away from how embarrassing the big trip was for all of us to watch (Pushing! Pope! Saudi bowing!) but...this?

'Honestly, hun this is so far over your head. If you need to have another "bone spur" and let Mike take over, no one will blame you.'

It is unknown who directly controls Trump's social media page, but another Twitter user, Holly O'Reilly, claims to have also recently been blocked by the account.

In lieu of a public statement on being blocked, Kalb shared a video of her cat on Instagram, saying: 'No mother should have to explain the President blocking her to her garbage sons.'
