An incorrect rumor shared by a Politico.com reporter in a disrespectful Tweet resulted in the reporter's termination.

It all started when CNN's Lisa Mirando tweeted: "Via @SaraMurray: Ivanka Trump to get office in same space reserved for First Lady in WH; Ivanka's title still TBD, per transition source".

Trump's transition team denied the rumor, saying, "This is false. No decisions regarding Ivanka’s involvement have been made".

But Politico reporter Julia Ioffe, pictured right, must not have received the memo.

She tweeted: "Either Trump is f**king his daughter or he's shirking nepotism laws. Which is worse?"

The shocking tweet was published by the Daily Caller in a post that was picked up by other conservative blogs.

By Wednesday evening, Ioffe was fired.

Politico released a statement saying Ioffe's "Tweet was a violation of the news site's standards.".

Ioffe was already transitioning out of Politico.com after she was hired by The Atlantic as their foreign policy and U.S. politics reporter.

She was set to start that job in January, but she had hoped to continue collecting paychecks from Politico.com until then.

There is no word on whether The Atlantic has a code of conduct policy in place, or if their high standards extends to their writers.
