Donald Trump threatened to fight to any House Democratic efforts to investigate the White House by saying he would counter with investigations “at the Senate level” following the midterm election that ensured the two chambers of Congress would be divided for the next two years.

“If the Democrats think they are going to waste Taxpayer Money investigating us at the House level, then we will likewise be forced to consider investigating them for all of the leaks of Classified Information, and much else, at the Senate level. Two can play that game!” Trump tweeted.

Democrats took back the majority in the House on Tuesday, while Republicans appear to have picked up at least three Senate seats, with others remaining too close to call.

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.

Trump is expected to deliver a news conference at 11:30 a.m. Wednesday morning on the midterm election results:

I will be doing a news conference at The White House – 11:30 A.M. Will be discussing our success in the Midterms!

Twitter quickly told Trump how it works:

"waste Taxpayers Money?" …like golf trips every weekend, rallies a couple of times a week… kinda like that, right?

You definitely sound like someone who thinks he won a big victory and not someone who is scared because he lost the Midwest, a house of Congress, and 7 governorships to a broad popular vote rejection. Really.

It’s not a game. You also don’t have a supermajority in the senate
