• Turning to trade, Mr. Trump said that Mrs. Clinton supported the North American Free Trade Agreement and cited China’s entrance into the World Trade Organization as evidence that his opponent will support deals that harm American workers. He also said that her record as secretary of state should be scorned because America’s trade deficit with China soared under her tenure.

Fact Check: As first lady, Mrs. Clinton privately expressed skepticism about Nafta, the trade pact that President Bill Clinton signed into law in 1993, though she made statements supportive of it. The trade pact has been widely blamed for the loss of American manufacturing jobs. Mrs. Clinton has called for parts of Nafta to be renegotiated and has said that the Trans-Pacific Partnership, President Obama’s 12-nation pact that she supported while serving as secretary of state, doesn’t meet her “high bar” on protecting American workers and the environment.

• Mr. Trump directly blamed Mrs. Clinton for the death of Ambassador J. Christopher Stevens in Benghazi, Libya, calling her a liar who ignored his requests for help. “Her decisions spread death, destruction and terrorism everywhere she touched,” Mr. Trump said, calling the rise of the Islamic State and chaos in the Middle East the fault of the former secretary of state.

• Mr. Trump changed his tone on Muslims, whom he has previously accused of being generally complicit in the violence carried out Islamic terrorists. “ISIS also threatens peaceful Muslims across the Middle East, and peaceful Muslims across the world, who have been terribly victimized by horrible brutality — and who only want to raise their kids in peace and safety,” he said.

• Mr. Trump suggested that Mrs. Clinton was responsible for making Iran the “dominant power in the Middle East and on the road to nuclear weapons.”

Fact Check: Iran is certainly a dominant power in the Middle East, but so is Saudi Arabia, and so is Israel. But Tehran is farther from nuclear weapons than it was a year ago, when Mr. Trump began his campaign. It has given up 98 percent of its nuclear fuel in the past year, and partly dismantled many of its nuclear facilities, under an accord that had its roots in Mrs. Clinton’s time as secretary of state.
