Fox News host Sean Hannity has begun losing advertisers amid heightened controversy surrounding his decision to draw attention to conspiracy theories about the death of Democratic National Committee staffer Seth Rich.

In recent weeks, Hannity has repeatedly pushed the claim that Rich was not the victim of a botched robbery, as authorities suspect, but rather that he was killed for providing Wikileaks with internal DNC emails.

There is no evidence suggesting this theory is true.

Hannity first raised questions about Rich's murder in August 2016, speculating about the possibility that Rich was a WikiLeaks source. Hannity has repeatedly called attention to the conspiracy theory over the past week as well.

Rich's family has repeatedly asked the cable TV host to stop peddling the rumor of a WikiLeaks connection.

On Tuesday, Hannity said that he would not discuss the Seth Rich story at this time "out of respect" for the family, but on Wednesday, he tweeted that he was "working harder than ever to get to the truth the family wants and deserves."

According to CNN media reporter Oliver Darcy, Fox News president of programming, Suzanne Scott, met with Hannity on Tuesday and "encouraged him to stop pushing" the Seth Rich conspiracy.

As of Wednesday night, Hannity continued talking about the case on his show, without mentioning Seth Rich's name.

Kim Guilfoyle, a co-host on Fox News' "The Five," said Wednesday that she would be filling in for Hannity for the next two days.

Here are the companies that have announced they will stop airing ads during Hannity's show:
