After working the local news beat for The Washington Post and becoming White House correspondent for The Wall Street Journal, Martin joined ABC News in 1992. At ABC, Martin reported for Nightline, and was awarded an Emmy for a report that aired on Day One. In 2001, she hosted the PBS show Life 360. Beginning in April 2007, she hosted Tell Me More for National Public Radio (NPR). As the host of Tell Me More, Martin focused heavily on topics of race, religion, and spirituality. Upon the announcement by NPR of the cancellation of Tell Me More, to be effective 1 August 2014, Martin blamed top leadership for failure to institutionalize support for the program and questioned NPR's commitment to serving African-American listeners and other people of color, admitting that she had "scar tissue" as a result of the cancellation. Martin and the show's producer, Carline Watson, remained with the network as, "part of an initiative to incorporate the kind of coverage of issues of race, identity, faith, gender and family that appear on the show". Since 2015, Martin has been the host of Weekend All Things Considered.
