Coming up on today’s show:

• The Democratic National Convention kicked off in Philadelphia on Monday. Takeaway Washington Correspondent Todd Zwillich is on the ground and brings us the latest from the convention floor, and explains what’s ahead for the rest of the week.

• Congresswoman Debbie Dingell represents Michigan’s 12th district. She delivers some sage advice for those who are expressing doubts about the mood emanating from Philadelphia this week.

• After Russian hackers exposed emails from the Democratic National Committee, Chairwoman Debbie Wasserman Schultz has stepped down. It’s the latest scandal to rock the Hillary Clinton campaign, and it raises questions about the ability of foreign entities to interfere with American elections. Anne Applebaum, a columnist for the Washington Post, weighs in. 

• Eroding economic conditions have severely impacted the poor and working class in the City of Brotherly Love. Bob Hennelly, an award-winning investigative reporter and political analyst, explains.

• Singer Marni Nixon, who died on Sunday at the age of 86, made a career dubbing vocals for well known stars. She sang the vocals for actresses in “The King and I,” “West Side Story” and “My Fair Lady,” just to name a few. Nixon told her story in the 2006 memoir, “I Could Have Sung All Night: My Story.” She produced the work with ghostwriter Stephen Cole. Cole, an award winning theatre writer, joins us in the studio today to remember Nixon. 

• Hillary Clinton’s nomination this week will signal a milestone in American history for California Congresswomen Anna Eshoo and Barbara Lee, and others like them who have also tried to break the glass ceiling of American politics. Together, Representatives Eshoo and Lee discuss their time in Congress, and the road ahead for women. 

• On the first night of the Democratic Convention, First Lady Michelle Obama delivered a passionate speech that rallied a divided party. For a look at Mrs. Obama’s convention speech and her legacy, we turn to Kate Andersen Brower, the author of “First Women: The Grace and Power of America’s Modern First Ladies.”
