Elon Musk brought his mom to a meeting with advertisers where he tweeted about Trump. He later fired an exec who didn't find the tweet funny, report says.

• Elon Musk went to New York on Halloween to meet with advertisers and visit a Twitter office.
• He brought his mom, Maye Musk, to the meeting, where execs asked about unbarring Trump.

Elon Musk brought his mom, Maye Musk, to a meeting with Twitter advertisers, Bloomberg reported Wednesday.

About 2 a.m. on Halloween, the Twitter CEO arrived in New York with plans to visit his company's office there and convince advertisers that the app was safe.

In the afternoon, he held a meeting with Horizon Media — a top ad agency that represents brands such as Burger King, Corona, and Geico. Two advertising executives from Twitter also came along, as well as Musk's friend Jason Calacanis and the older Musk.

Calacanis is a tech investor who was part of Musk's inner circle at Twitter — giving him advice on the company — but never holding an official position. After mass layoffs, staffers were told to listen to Calacanis' podcast to understand why the cuts were necessary.

It is unclear why Musk's mother went to the meeting. Later that night, she accompanied her son to a costume party hosted by Heidi Klum.

The older Musk appeared with her billionaire son at this year's Met Gala and on "Saturday Night Live" in May.

Horizon Media CEO Bill Koenigsberg told Musk that some of his clients had heard about the meeting, according to Bloomberg. He said: "They all asked, 'Is he going to get Donald Trump back on the platform?'"

Musk answered that many people were asking him the same question before pulling out his iPhone and composing a tweet during the meeting: "If I had a dollar for every time someone asked me if Trump is coming back on this platform, Twitter would be minting money!"

Musk paused before posting and asked everyone in the meeting whether they liked his joke, Bloomberg reported. One Twitter executive was opposed to the tweet, but Musk laughed and posted it anyway. The executive was fired later that week, Bloomberg added.

Twitter and Horizon Media did not immediately reply to requests for comment, which were sent outside normal working hours.
