"I probably will be bringing a lot of litigation against a lot of people having to do with the corruption investigation having to do with the 2016 election," Trump told a joint news conference with Finnish President Sauli Niinistö.
Trump did not name names but has long expressed frustration at some of the central figures in the investigation by U.S. Special Counsel Robert Mueller such as former FBI Director James Comey.
Trump fired Comey in May 2017.
The Mueller probe found insufficient evidence to establish that Trump and his campaign had engaged in a criminal conspiracy with Russia.
The Russian state did run a hacking and propaganda operation to disrupt the U.S. election, Mueller found.
America waited with bated breath for two years to hear whether the Trump campaign colluded with Russia in the 2020 election. The leader of the investigation was former special counsel Robert Mueller, who testified before Congress and has made few public statements since then. But according to Business Insider, Mueller on Tuesday issued a statement refuting claims made by his former right-hand-man, Andrew Weissman.
The United States on Thursday imposed sanctions on a pro-Russian Ukrainian lawmaker linked to Republican efforts to dig up dirt on Democratic presidential candidate Joe Biden and his son Hunter, accusing him of trying to interfere in the U.S. election. This report produced by Chris Dignam.
