Sens. Chuck Grassley (R-Iowa), Ron Johnson (R-Wis.,), and Lindsey Graham (R-S.C.) continued a 2017 investigation into possible collusion and other crimes committed by Democrats against President Donald Trump’s campaign in 2016.

In particular, they are investigating a request made by a consultant to the Democratic National Committee, that members of the Ukrainian government would have worked against candidate Donald Trump in favor of candidate Hillary Clinton.

“Election interference by any foreign entity is a serious matter,” Senate Finance Committee Chairman Grassley wrote on his Senate page.

“Whether there’s a connection between Democratic operatives and Ukrainian officials during the 2016 election has yet to be determined,” Grassley added.

The senators are interested in transcripts of conversations from then-Democratic National Committee (DNC) consultant Alexandra Chalupa.

They are also looking for the text of an interview between Andriy Telizhenko, a political official of the Ukrainian Embassy at the time, and members of Hillary’s campaign.

The president of the Senate Judiciary Committee, Graham, spoke in this regard.

“Whether there’s a connection between Democratic operatives and Ukrainian officials during the 2016 election has yet to be determined. It will only be found by looking. We intend to look,” he said according to CBS.

Grassley and Johnson also requested information from the National Archives about the 2016 White House meetings between representatives of the Obama administration, the Ukrainian government, and the DNC.

U.S. intelligence officials and special counsel Robert Mueller discovered that Russia had hacked into the DNC.

“It’s deeply unusual for an American campaign to be working with foreign assets like this, regardless of whether it’s Ukraine or Russia,” CBS News reported on Dec. 6 on an analysis done in 2017.

The Democrats promoted a major investigation against the campaign of the then candidate Donald Trump for possible collusion with Russia, which was completely ruled out according to the report presented by special counsel Robert Mueller.

The Republican senators’ inquiries take place within the framework of the controversial impeachment that the Democrats are conducting against President Donald Trump.

The White House Press Office warned House Speaker Nancy Pelosi that by offering her support for President Trump impeachment, she was “ignoring the needs of the American people and advancing her selfish political desires.”

“Democrats in Congress have clearly abused their power. Democrats in Congress have lied to the American people. Democrats in Congress have made a mockery of the law,” the press office said in a Dec. 5 statement.
