Tuesday in politics: Napolitano testifies at immigration hearing, and more

Mike Emanuel reports from Capitol Hill

The Senate Judiciary Committee continues work on the immigration reform bill Tuesday with testimony from Secretary of Homeland Security Janet Napolitano.

It will be the committee’s third hearing on the legislation, which was unveiled last week.

[Senators argue over whether bombing should influence immigration reform]

Monday’s hearing was marked by a heated discussion over whether the deadly bombings in Boston, allegedly by two brothers who emigrated from Eastern Europe, should influence the immigration reform debate.

Also worth noting on Tuesday: President Barack Obama meets with Qatar Amir Hamad bin Khalifa al-Thani at the White House; Obama honors the 2013 National Teacher of the Year and finalists; Stephen Colbert hosts a fundraiser for his sister, Elizabeth Colbert Busch, the Democratic candidate in South Carolina's 1st Congressional District May 7 special election; and first lady Michelle Obama visits the Department of the Interior to thank employees for their public service.

And then there is this: Obama will dine with all 20 women senators at the White House on Tuesday evening. The meal is the latest in Obama's outreach to lawmakers.
