Rep. Cummings is very angry at Trump's response to this demand from Democrats

Rep. Elijah Cummings (D-Md.) fired off an angry statement denouncing the White House response to his demand for documents and interviews, but he fell short of calling for a subpoena.

Cummings, who is the chairman of the House Oversight and Reform Committee, said the refusal to answer his committee's demands was a violation of the checks and balances set forth in the Constitution.

"There is a key difference between a president who exercises his authority under the Constitution and a president who overrules career experts and his top advisers to benefit his family members and then conceals his actions from the American people," Cummings asserted in a statement.

"The White House's argument defies the Constitutional separation of powers," he added, "decades of precedent before this Committee, and just plain common sense. The White House security clearance system is broken, and it needs both congressional oversight and legislative reform."

The committee has the power to compel the White House to answer by issuing a subpoena, but Cummings only vaguely threatened to consider the option.

"I will be consulting with Members of the Committee to determine our next steps," he concluded.

The committee is investigating reports that President Donald Trump possibly interfered in order to assure that his daughter Ivanka Trump and his son-in-law Jared Kushner received security clearances that they may not have qualified for otherwise.
