WASHINGTON (AP) — The Latest on President Donald Trump's speech to the conservative Heritage Foundation (all times EDT):

7:40 p.m.

President Donald Trump is using his appearance in front of a conservative think tank to argue the U.S. should celebrate and preserve its history, "not tear it down."

Trump is pointing to a movement to take down Confederate status as well as other symbols of the country's difficult past.

He says, "Now they're even trying" to take down statues of Christopher Columbus. He asks, "What's next?"

Trump also says young Americans should be taught to honor the flag and national anthem and proudly recite the Pledge of Allegiance.

He tells the group, "You understand that our glorious heritage is the foundation of everything we hope to achieve."

President Donald Trump is taking his tax plan sales pitch to the conservative Heritage Foundation.

Trump is expected to tell the group's President's Club on Tuesday evening that his plan will be a boon to the economy, resulting in a $4,000 pay raise for the average American.

That claim has been met with skepticism from tax experts and Democratic lawmakers who say the administration's math is flawed.

Trump is also expected to talk about other issues important to the group, including the Constitution, his appointment of conservative judges, border security and his "peace through strength" foreign policy approach.

That's according to a senior administration official who previewed the speech earlier Tuesday on condition that he not be named.
