The US Justice Department submitted to the House Judiciary a summary of the results of the investigation by Muller of US President Donald Trump's 2016 presidential campaign and suspicions of cohesion between Russia and Russia.

Democratic Party chairman Gerald Nadler said that he received a "very simple letter" about Robert Mueller's investigation report.

US media reported that Muller did not prove that Trump Camp or his associates had collaborated with Russia.
