While working for DHS he was openly lobbying members of both Qatar and the UAE Governments trying to get them to hire him. Both governments reported it because they were confused why he was pressuring them when they already had existing relationships with the US, but it was because he wanted them to bribe him.
Palantir negotiated a 2.7 billion deal with DHS, a blanket PO. After the deal was done Lewandoski repeatedly pressured the CEO Alex Karp to meet with him, when Karp refused, DSH reduced the deal from 2.7 billion to 1 billion.
