It takes a very small amount of research to note how often Google visited the White House, how much money Google invested in political campaigns over the last number of years, and how FTC staff found more than adequate reason for an antitrust investigation of Google until the White House ordered it dropped. Eric Schmidt, the chairman of Google's board, was considered part of Hillary Clinton's campaign staff and personally funded the company that provided a lot of the Clinton campaign's web dev.

I think this is a pretty bold claim and would appreciate the sources you found probative.
If the statements you offer constitute sufficient evidence for you, I would say that numerous companies and industries have more contact with our lawmakers than what you have described.
'Google executives set foot in the Obama White House more often than those of any other corporation – its head lobbyist visited 128 times. Google spread its money across Washington with joyous ecumenicism. Google spent about $17m on influence peddlers of both partisan varietals. By one count, Google poured more into its DC apparatus than any other public company.'
As I stated, I was providing you with more detailed statements for you to do your own research. My comment was intended as a starting point, not a bible on the topic.
