A writer for American comedy show Saturday Night Live has been suspended after posting a tweet mocking US President Donald Trump's son Barron, US media reports say.
The reports say Katie Rich has been suspended indefinitely but the programme's network, NBC, is yet to comment.
On Saturday, Ms Rich posted a now-deleted tweet, saying "Barron will be this country's first home-school shooter".
An avalanche of criticism on social media followed.
Ms Rich later deleted her tweet, suspending her Twitter account.
However, she was back online today to issue an apology.
I sincerely apologize for the insensitive tweet. I deeply regret my actions & offensive words. It was inexcusable & I'm so sorry.— Katie Rich (@katiemaryrich) January 23, 2017
One Facebook post in reaction to her previous tweet has been shared nearly three million times.
The post read: "NO child deserves to be talked to in such a manner... He is a child, he is to be respected and he is off limits."
Chelsea Clinton, a former first child, joined the support for Barron.
Barron Trump deserves the chance every child does-to be a kid. Standing up for every kid also means opposing @POTUS policies that hurt kids.— Chelsea Clinton (@ChelseaClinton) January 22, 2017
Saturday Night Live has made a number of shows in recent months, parodying Mr Trump.
Mr Trump, who took office on 20 January, has described the programme as "not funny" and with a "terrible" cast.
