Dissembled:
to hide your real intentions and feelings or the facts:
He accused the government of dissembling. [Cambridge Dictionary]
Noted in a letter written by Members of the Intelligence, Oversight and Reform, and Foreign Affairs Committees to their colleagues in Congress:
For example, Secretary of State Pompeo has now admitted that he was on the call when President Trump explicitly pressed the Ukrainian President to investigate the Bidens – but failed to report this to the FBI or other law enforcement authorities. You will recall, FBI Directory Christopher Wray urged individuals to report efforts to seek or receive help from a foreign power that may intervene in a U.S. presidential election.
This obligation is not diminished when the instigator of that foreign intervention is the President of the United States; it is all the more crucial to the security of our elections. Instead, when asked by the media about his own knowledge or participation in the call, Secretary Pompeo dissembled.
