VIDEO: Trump and Jeb Bush on presidential campaign trail

Republican Presidential candidates Donald Trump and Jeb Bush both delivered speeches on Tuesday to state their cases for why they should be the next president of the United States.

Trump spoke for 50 minutes to more than 2,000 people at a Republican fundraising dinner in Birch Run, Michigan.

It was his first public appearance since the first GOP primary debate and his first appearance as a presidential candidate in Michigan.

In Simi Valley, California, Bush stepped up his criticism of Hillary Rodham Clinton and her tenure as Secretary of State, arguing in a speech that the Democratic front-runner shares in the mistakes that he said has led to the rise of the Islamic State group (IS).
