The House majority gives Democrats subpoena and investigatory power, posing potential headaches for the White House. Top Democratic lawmakers have vowed to demand the president's tax returns and investigate other aspects of his presidency if they regained the majority.

The additional GOP Senate seats could provide a cushion for Trump to get his Cabinet appointees and judicial nominees confirmed.

The president is scheduled to hold a press conference at 11:30 a.m. Wednesday to discuss the midterms.
