The job of a US senator is best expressed by the oath of office they take: “I do solemnly affirm that I will support and defend the Constitution of the United States against all enemies, foreign and domestic; that I will bear true faith and allegiance to the same; that I take this obligation freely, without any mental reservation or purpose of evasion; and that I will well and faithfully discharge the duties of the office on which I am about to enter: So help me God.”
The actual day-to-day duties of a Senator are: "Senators, along with members of the House of Representatives, propose, author, and vote on federal legislation that touches upon all aspects of U.S. domestic and foreign policy. Senators provide advice and consent on executive nominations and treaties and conduct oversight of all branches of the federal government."
I realize that few if any senators take their oath seriously, but it's still wrong to say that they are doing their jobs when they do the wrong thing.

Note that's quite different from saying senators should serve the interests of a national government.
Of course, I doubt it'd come as a surprise to anyone that these payloads are likely insanely expensive as they too have gone through the govt procurement system (which seems to make everything cost 100x what it should cost). At which point it makes sense to avoid losing the payload even at ULA pricing.
$350x1.00 = $350 million for ULA $100x(1/.95) = $105.2 million for SpaceX
The difference is then $245 million or so. So, the government needs to justify why reducing their risk from 5% to 0% on losing a payload is worth $245 million. Purely economically, the payload would need to be worth about $4.9 billion to justify this cost. If we start talking about State secrets, actual production time for the payload on top of the economic cost, redundancy requirements for intelligence gathering, technological advantage over rival powers (China/Russia) that could be lost if another country recovers the wreckage, and the worth of a citizen's/soldier's life on the front line (e.g. - items that are hard to quantify economically) and you can see how easy it is to justify $245 million.
Plus your buddy works at ULA and it would suck if he had to work somewhere else because they went out of business.
Their job is to represent the interests of their state or their constituency.
Otherwise, their constituency would vote them out.
These senators are working at cross-purpose with our broader national interests.
