False premise. I don't know that the Russians helped Trump win (whatever that means). Many people celebrated Hillary's defeat for obvious reasons. Nothing nefarious in that. More importantly, there is no evidence that any of Trump's policy decisions were influenced by the Russians. He certainly tried to appeal to Putin's ego with good result. No invasion of Ukraine.
Specious reply.
Have you read the Mueller Report or the Senate Intelligence Committee Report?
Here's an excerpt from the Wikipedia article on the latter:
The Republican-led Senate Intelligence Committee submitted the first part of its five-volume report in July 2019 in which it concluded that the January 2017 Intelligence Community assessment alleging Russian interference was "coherent and well-constructed." The first volume also concluded that the assessment was "proper," learning from analysts that there was "no politically motivated pressure to reach specific conclusions." The final and fifth volume, which was the result of three years of investigations, was released on August 18, 2020,[6] ending one of the United States "highest-profile congressional inquiries."[7][8] The Committee report found that the Russian government had engaged in an "extensive campaign" to sabotage the election in favor of Donald Trump, which included assistance from some of Trump's own advisers.[7]
