EXCLUSIVE — The Democrats who were seen waving Ukrainian flags on the House floor after passing a billion-dollar foreign aid package could face an ethics investigation after a request made by the conservative Heritage Foundation demanded accountability for the lawmakers. 

In a letter sent to the House Ethics Committee on Wednesday, the Heritage Oversight Project requested an investigation into 28 House Democrats who waved Ukrainian flags inside the House chamber, which the group argued violates congressional decorum rules. The request presses the committee to look into the allegations and “hold the wrongdoers accountable,” according to the letter, which was first obtained by the Washington Examiner.
