Answer:
If a government official changes his vote on a particular amendment or vote, in exchange for a high paying job in government once they leave congress, it can be said that they were swayed by unproper government interference.
In other words, some government officials carried out a form of illegal lobbying to change the positions of the congresspeople. This is illegal or unproper because the constitution establishes that the U.S. Congress and the U.S. Government should be independent, check each other's power, and collaborate, but in a genuine manner, without unproper influence.
