President Trump threatened that if a Democrat-led House "[wastes] Taxpayer Money investigating us...we will likewise be forced to consider investigating them...at the Senate level" in a Wednesday morning tweet.
"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!"
The big picture: Axios' Jonathan Swan reported in August that House Democrats were preparing a wishlist of investigations they hoped to initiate if they won the majority, which House Democratic Leader Nancy Pelosi confirmed was coming in her post-midterms victory speech, promising to restore "the Constitution’s checks and balances to the Trump administration."
