Cable news opposites Rachel Maddow and Tucker Carlson have a shared history.
Maddow recently credited Carlson with giving her a foot in the door at MSNBC when she was a panelist on his show "The Situation with Tucker Carlson" from 2005 to 2008. At the time, she was a talk show host on Air America Radio.
"The first show I worked on was his 11 o'clock show on MSNBC that nobody remembers. But he was always kicking around the business and has always been talented. It just — this turned out to be his moment," she said in an interview with Vanity Fair.
According to the New Republic, Carlson's team brought Maddow onto his show in 2005, and he insisted on keeping her around even though "she didn't look like a Fox blonde," a style reportedly preferred by MSNBC's then-president.
When Carlson was later hired at "Fox and Friends" in 2013, Maddow told Salon, "Tucker and I agree on just about nothing, but he has always been kind to me, and a fun person to fight with. I wish him all the best."
Carlson would then go on to host "Tucker Carlson Tonight" on Fox News, and Maddow "The Rachel Maddow Show" on MSNBC.
Here's a look-back into their time together on-air where they regularly quipped and exchanged laughs amid their fiercest debates.
