The Democrats have been trying to overthrow a duly elected president using gossip and intrigue, since Trump took office. Trump threatens their money making scams, that allows the Swam to steal from the tax payer, without them even knowing about it. Trump knows how the swamp works, and the swamp is trying retain its ill gotten gain, even if this involves criminal activity. .
Former Vice President Biden is a good case study of how the tax payer is being ripped off by the left. The US gives foreign aid to countries like Ukraine. This seems fine. But the money is being given to a corrupt government, so the money can be skimmed. Biden through his son, got some of this tax payer money, through a large third party business, who received US tax payer money from the Ukraine government. It is a tax payer money laundering scam via foreign aid.
Global warming and climate change was supposed to involve $trillions of tax payer money, given all over the world, even to third world dictators known for corruption. This flow of money was supposed to create a huge slush fund. It was basically a money laundering scam for Democrat middle men, to skim. Trump messed-up that scam, and now they are out to get him, so they can restore this huge tax payer funded slush fund.
All the cash given to Iran, had an attached processing fee for a slush fund. Iran will launder this money and some will be transferred later so it looks legitimate. Trump is being threatened with impeachment because he was trying to expose the scam in Ukraine.
