WASHINGTON (AP) President Joe Biden will establish a national monument honoring Emmett Till , the Black teenager from Chicago who was abducted, tortured and killed in 1955 after he was accused of whistling at a white woman in Mississippi, and his mother, a White House official said Saturday.

Biden will sign a proclamation on Tuesday to create the Emmett Till and Mamie Till-Mobley National Monument across three sites in Illinois and Mississippi, according to the official. The individual spoke on condition of anonymity because the White House had not formally announced the presidents plans.

Tuesday is the anniversary of Emmett Tills birth in 1941.

The monument will protect places that are central to the story of Tills life and death at age 14, the acquittal of his white killers and his mothers activism. Tills mothers insistence on an open casket to show the world how her son had been brutalized and Jets magazines decision to publish photos of his mutilated body helped galvanize the Civil Rights Movement.

Bidens decision also comes at a fraught time in the United States over matters concerning race. Conservative leaders are pushing back against the teaching of slavery and Black history in public schools, as well as the incorporation of diversity, equity and inclusion programs from college classrooms to corporate boardrooms.

On Friday, Vice President Kamala Harris criticized a revised Black history curriculum in Florida that includes teaching that enslaved people benefited from the skills they learned at the hands of the people who denied them freedom. The Florida Board of Education approved the curriculum to satisfy legislation signed by Gov. Ron DeSantis, a Republican presidential candidate who has accused public schools of liberal indoctrination.

How is it that anyone could suggest that in the midst of these atrocities that there was any benefit to being subjected to this level of dehumanization? Harris asked in a speech delivered from Jacksonville, Florida.

DeSantis said he had no role in devising his states new education standards but defended the components on how enslaved people benefited.

All of that is rooted in whatever is factual, he said in response.

The monument to Till and his mother will include three sites in the two states.

The Illinois site is Roberts Temple Church of God in Christ in Bronzeville, a historically Black neighborhood on Chicagos South Side. Thousands of people gathered at the church to mourn Emmett Till in September 1955.

The Mississippi locations are Graball Landing, believed to be where Tills mutilated body was pulled from the Tallahatchie River, and the Tallahatchie County Second District Courthouse in Sumner, Mississippi, where Tills killers were tried and acquitted by an all-white jury.
