The Republican field gets more crowded today with Wisconsin Governor Scott Walker expected to throw his hat in the ring. Wisconsin just passed a controversial budget after a long delay, and Walker is expected to formally announce at an event in Waukesha, Wisconsin at 6:15pm. He’s also already sort of announced via an online video. He becomes an instant front-runner. Reid Espstein in the Wall Street Journal writes, “Scott Walker will formally announce his presidential bid Monday, launching an effort built around his belief that the best way for Republican candidates to win is by better energizing their conservative base rather than by moving toward the center. The Wisconsin governor's announcement will mark the entry of another big name in an exceptionally crowded GOP field. Mr. Walker, who becomes the 15th declared major candidate, is widely considered to be in the top tier along with Sen. Marco Rubio (R., Fla.) and former Florida Gov. Jeb Bush.”

Jeb Bush, John Kasich and Rick Perry also holding events today. We’ll monitor for news.

Donald Trump gave a fiery speech over the weekend in Phoenix. He’s doubling down on anti-immigration policy.

Hillary Clinton is giving a big economic policy speech today at 10am. It’s her first big policy speech. She’s expected to move to the left on economic policy though she’s avoiding some of the more controversial proposals being put forth by Vermont Senator Bernie Sanders as he rallies liberals to his redistribution of wealth arguments. He’s providing some serious competition for Clinton from her left flank. Ed Henry reporting.

The Wall Street Journal’s Laura Meckler writes, “In an economic speech Monday, the Democratic presidential front-runner will focus on her differences with Republican rivals. She will accuse them of seeking growth without regard to whether the middle class thrives, and say that raising incomes for all Americans is "the defining economic challenge of our time," a campaign aide said.”
