The whole thing is ridiculous.
For starters, the meeting was initiated by a British TABLOID writer/publicist. It's like a British equivalent of Perez Hilton emailing Donald Trump Jr to set up a meeting between him and a "Kremlin lawyer". Except the lawyer is not working for Kremlin, but for a firm that works with Clintons.
Meanwhile, you have all these leakers from the previous administration like Reality Winner and James Comey that used NSA spying as a political tool against their opponents. A strong indication that the corruption at home is far more cancerous than any foreign meddling attempt.
