A coalition of Democratic lawmakers are asking tech giant Palantir to turn over details of their contracts with the Trump administration amid reports the data company has been given lucrative contracts that could allow it to assemble a database on Americans.

The New York Times reported last month that Palantir is in discussions with numerous government agencies for use of its technology that analyzes data, including the Social Security Administration and the Internal Revenue Service (IRS).

According to the lawmakers, the company “is enabling and profiting from serious violations of Federal law by the Trump Administration, which is amassing troves of data on Americans to create a government-wide, searchable ‘mega-database’ containing the sensitive taxpayer data of American citizens.”

According to the Times, Palantir has taken in more than $113 million in federal government spending under President Trump, as its Foundry data and analytics technology is already in use at the Department of Homeland Security and the Department of Health and Human Services.
