Welcome to your campaign trail guide, a daily tour through the twists and turns of the 2016 presidential campaign. It's Monday, July 13 and here’s what we’re watching:
- Wisconsin Gov. Scott Walker announced his candidacy in a video Monday morning and will make it official at a rally later today in the Milwaukee suburb of Waukesha. Walker will be the 15th declared Republican candidate in the race. Welcome, Governor.
- Hillary Rodham Clinton will outline her economic policies in a speech at the New School in Manhattan. She’ll lay out a plan that targets "excessive risk taking" on Wall Street and tries to help the economy grow “faster, fairer and more sustainably,” her campaign says.
