Up to one million migrants are expected to have entered the United States under the controversial CPB One program by the time President Joe Biden leaves office, with the figure already nearing 900,000, according to internal Department of Homeland Security data obtained by the Washington Free Beacon.

CBP One allows migrants who want to claim asylum in the United States to apply for the program in their home country using a mobile phone application. Those migrants are then given court dates, which are often scheduled years later. The Biden administration broadly expanded the program last year under the belief that it would ease pressure on the southern border.

That decision prompted criticism from Republicans who said CBP One was nothing more than a way to facilitate illegal immigration and mask the true number of individuals entering the country. Migrants who enter the country via CBP One are not counted by law enforcement agencies as traditional border crossers.

But few are aware of the scale of CBP One. Data obtained by the Free Beacon show that more than 880,620 migrants have been processed with the program since Nov. 2, 2023.
