David Axelrod, the former White House senior adviser and senior strategist for both of Barack Obama's presidential campaigns, has signed on with NBC News and MSNBC as a senior political analyst, NBC said Tuesday.

In his new capacity, Axelrod will be a frequent contributor across all broadcasts and platforms for both outlets.

Axelrod, who has worked on political campaigns for almost 30 years, started his career as a journalist with the Chicago Tribune, spending eight years at the paper as a political writer, columnist and City Hall bureau chief before switching to a career in politics in 1984.

Axelrod's new gig places him on the same side of the fence as his former political adversary Steve Schmidt, the senior adviser of senator John McCain's 2008 presidential campaign who now serves as a political analyst for NBC News and MSNBC.

The companies' roster of analysts also includes former RNC Chairman Michael Steele and former Pennsylvania Governor Ed Rendell.
