Why did the US agree to take on $3.25 million in claims as part of the Treaty of Guadalupe Hidalgo?

The United States agreed to assume $3.25 million in claims owed by Mexico to American citizens. These citizens had financial claims against the Mexican government, and the treaty transferred responsibility for paying them to the United States. The payment was not repayment of Mexico’s debts to European countries or compensation to Mexico for the land.
