It's not so much as Russia doing this, it's more of Trumpette knowing and saying nothing.The Lincoln Project is not a credible source for anything other than as a place to satiate a certain confirmation bias.
The report comes from the New York Times, who used unnamed sources with information that nobody else in the room knew about. That alone should tell you that it is almost certainly fake news. That the Lincoln Project has something to say about it is less than meaningless.
But let's say Russia did pay the Taliban to attack and kill Americans. So what? Do you think the Taliban is self-funded? Do you think this is the first time in the history of history that an adversary has given money or arms to another to be used against a mutual adversary? Do you think this is the first time Russia has given money or arms to be used specifically against the United States? I'm shocked, shocked, I tell you, that Russia would do this.
