The Latest: Trade order, campaign rally on Trump's 100th day

WASHINGTON (AP) - The Latest on President Donald Trump's 100th day in office Saturday (all times EDT):

12:25 p.m.

President Donald Trump is marking his 100th day in office by saying he's brought - in his words - "profound change" to Washington, and he's reaffirming that "my only allegiance" is to those he governs.

Later on Saturday, he's going to visit Pennsylvania, one of the states that propelled his unlikely election victory.

Trump plans to sign an executive order directing the Commerce Department and the U.S. trade representative to conduct a study of U.S. trade agreements.

Trump is set to visit the Ames tool factory in Camp Hill, Pennsylvania, which has manufactured shovels since 1774, and then hold a campaign-style rally in Harrisburg, the state capital.

President Donald Trump is marking his 100th day in office by talking tough on trade.

The White House says the president intends to sign an executive order Saturday that will direct the Commerce Department and the U.S. trade representative to conduct a comprehensive study of the nation's trade agreements.

The aim is to determine whether America is being treated fairly by its trading partners and the 164-nation World Trade Organization.

Trump is heading to Pennsylvania in the evening to visit a shovel factory and appear at a rally in Harrisburg, the state capital.
