Washington (CNN)There are growing concerns inside the White House and among GOP leadership that Democrats will immediately seek to impeach President Donald Trump should Republicans lose control of the House this November, six White House and congressional sources tell CNN.

“POTUS is aware” of the concern, one White House source said, describing the hand-wringing inside the West Wing over the upcoming midterms as “the anticipation of death.”

Hoping to avert that potential scenario Trump is expected to campaign hard for House Republicans in the November elections, the source said, citing internal White House planning.

“(Trump) doesn’t want anyone to say he didn’t fight hard to keep the House,” the source added.

“Let the investigation play out. In the meantime, our focus should be on demonstrating why we will do more for families than the GOP and expose the reckless waste and abuse of government resources in this administration,” former Hillary Clinton campaign manager Robby Mook told CNN. “We do that by subpoenaing records and getting them out in the open so taxpayers can see how badly they’re being ripped off.”
