The panel is investigating Russian interference in the election and any contacts between the Trump campaign and Russia. The top Democrat on the panel, Adam Schiff, said afterwards that Ms Hicks had answered questions about the election campaign and had answered some questions about the transition period between the election and the inauguration – but that she would not answer any questions about events since the Republican took the oath of office, similar to some other White House officials who have given evidence. Mr Schiff said Ms Hicks did not assert any type of executive privilege, but that she said had received legal advice not to answer.
