President Joe Biden will designate a new national monument to honor to Emmett Till and his mother, Mamie Till-Mobley, this week amid slipping approval ratings among black voters, a critical contingent of the Biden coalition.

On Tuesday, the 82nd anniversary of Till's birth, Biden will sign an order designating the new memorial across three sites in Illinois and Mississippi. One will be at Roberts Temple Church of God in Christ in Chicago, which held Till's funeral service in September 1955. A second will be located at Graball Landing in Mississippi, where Till's body was located. The third memorial will be designated at the Tallahatchie County Second District Courthouse, where Till's killers were acquitted.

BIDEN CAMPAIGN COULD COUNT ON THESE SURROGATES TO EXCITE VOTERS ABOUT REELECTION

"The new monument will protect places that tell the story of Emmett Till's too-short life and racially motivated murder, the unjust acquittal of his murderers, and the activism of his mother, Mamie Till-Mobley, who courageously brought the world's attention to the brutal injustices and racism of the time, catalyzing the civil rights movement," White House press secretary Karine Jean-Pierre told reporters during Monday's press briefing. "This will be the president's fourth new national monument since taking office. That designation reflects the Biden-Harris administration's work to advance civil rights and commitment to protecting places that help tell a more complete story of our nation's history, and it comes at an important moment."

Jean-Pierre proceeded to call out Florida officials for "promoting a lie that enslaved people actually benefited from slavery."

"It's inaccurate, insulting, it's hurtful and prevents an honest account of our nation's history," she continued. "We will not stand for it. The Biden-Harris administration will continue to speak out against hateful attempts to rewrite our history and strongly oppose any actions that threaten to divide us and take our country backwards."

Biden has taken significant steps since entering office to fulfill campaign promises to this crucial voting bloc, including placing black women in top administration posts and on the Supreme Court bench. Still, the president has failed to keep some of his other campaign promises, like police reform and signing voting rights legislation into law.

Though the roughly 70% approval rating the president currently enjoys is higher than at earlier points this year, the demographic presents more concerning data points for Biden.

A May poll from Ipsos and the Washington Post showed that just 34% of black Americans believe that Biden's agenda has helped their community. Nearly a majority of black respondents said his policies have had no impact, and 14% say the president's agenda is harming black people.

And a poll conducted by YouGov and the Economist found that only 46% of black respondents wanted Biden to seek a second term, compared to 56% of all Democrats.

Biden's polling dip is not restricted to black voters. His overall approval rating has been underwater since the U.S. withdrawal from Afghanistan in the summer of 2021, and his average approval rating among white and Hispanic voters has dropped roughly 10 and 25 points, respectively, since January 2021.

The president's support among all demographics is tightly tied to the economy. Though Biden's economic polling is similarly poor, as the RealClearPolitics polling aggregate showed Biden's economic approval at 38% Monday, the administration is optimistic about several economic metrics.

There is a sense inside the White House that some of the negative sentiment is being driven by Republican respondents who will always say the economy is suffering unless there's a Republican in the White House. One senior White House official suggested to the Washington Examiner that the president's team is focused on its "long-term" vision for the country.

Jean-Pierre offered similar logic when questioned on the timing of Tuesday's designation, given claims by activists levied against Republicans in states like Florida and the president's apparent lack of attention to the issue.

"You'll hear directly from the president, and he'll continue to speak to this. One of the four crises that he talked about when he walked into this administration was racial injustices that we were seeing in this country and how we needed to continue to fight and we needed to continue to uplift what we're seeing across the country over the past couple of years, not just a couple of years but over what we have seen over the past decades," she told reporters. "And so this is a president that doesn't shy away from that and is going to continue to speak up."
