Schumer cited comments by Trump's personal attorney John Dowd on Saturday asking the deputy attorney general to "bring an end" to the "fraudulent" investigation he claimed was constructed to undermine the president.

"The president, the administration, and his legal team must not take any steps to curtail, interfere with, or end the special counsel's investigation or there will be severe consequences from both Democrats and Republicans," Schumer said in a statement.
