Calls for immigration reform are heating up today. Rallies are set this afternoon in Washington DC — and in communities up and down California — in support of reform. Tens of thousands of immigrants and their supporters are expected to turn out in DC alone.

KPCC's Washington Correspondant Kitty Felde updates us on where things stand this morning. 

Plus, the American Action Forum, a conservative think tank, recently released some surprising research. They report that immigration reform might actually boost the economy, not hurt it. We’ll speak to the group’s president, economist Douglas Holtz-Eakin.
