The “meddling” was the publication of the Podesta files. Had they made the allegation, they would have had to back it up while disclosing the info was prima facia evidence of felonies committed by the administration and the DNC.
Even if the Russians were involved in hacking the DNC - so what. It hardly rises to the level of "influencing" the U.S. election. Ninety percent of voters have never even heard of the DNC or that little leftist weasel John Podesta.
As if our own government hasn’t “meddled” in foreign elections and actually deposing foreign governments, either legitimately elected or they legitimately stole their positions. Ask President Arbenz of Guatemala (oh, he’s dead); Ask President Allende of Chile (oh, he’s dead); ask the Diem brothers in South Vietnam (oh, they’re dead); ask Saddam Hussein and his non-existent weapons of mass destruction (oh, he’s dead); ask Moammar Qaddhafi (oh, he’s dead); ask Mohammed Mossadegh, PM of Iran in 1953 (oh, he’s dead); ask Moishe Tshombe in Katanga Province of the Congo (oh, he’s dead). Ask the Communists in Portugal and Italy who were on their way to winning parliamentary elections until the CIA conducted a disinformation campaign. I’m not saying that some of these interventions were not justified, only that the “meddling” by the US went far beyond whatever it is that the Russians are accused of and which the bozos in the Senate and the lib Dems in the House seem to be in a tizzy over. There’s a bit too much of “do as I say and not as I do” here.
