The Senate Intelligence Committee updated the American public on Wednesday regarding the ongoing investigation into Russia's interference in the 2016 election, with chairman Richard Burr (R-N.C.) saying the "issue of collusion" remains open, ABC News reports.

Burr admitted, though, that the committee is not making the kind of progress it would like; the investigation has "hit a wall" in regards to the Christopher Steele dossier. The documents, originally leaked by BuzzFeed News, allege that the Russian government had material it could use to blackmail President Trump. Steele, a former British spy, has refused to talk to the Senate. "[Special Counsel Robert] Mueller [is] less likely to hit a wall on compelling witnesses," tweeted MSNBC's Ali Melber.

Additionally, "Burr reiterated that 'no vote totals were affected'" by any sort of meddling, "but stressed that the Russian interference in U.S. elections is ongoing and will continue in subsequent elections," ABC News writes. Jeva Lange
