Three Democratic senators have requested that two companies, Salus Worldwide Solutions and Geo Group, preserve records of their communications with Corey Lewandowski. This follows a report that the companies were allegedly asked to pay him in exchange for contracts with the Department of Homeland Security. The private prison firm is contracted by DHS to house undocumented immigrants and is the ranking member on the Senate Permanent Subcommittee on Investigations. It is unclear if Lewandowski received any money from businesses contracting with the government. The DHS inspector general has expanded his investigation into the awarding of a $220 million contract for a department advertising campaign featuring then-Homeland Security Secretary Kristi Noem.
