She can take her chances with SCOTUS (and hope they take up the matter quickly) or take a vote in the House. What is she afraid of?

WASHINGTON — The White House is planning to spurn Democrats' request for documents sought as part of their impeachment inquiry as administration aides scramble to calibrate a legal response strategy.
White House lawyers plan to argue that until there is a formal vote by the House to begin impeachment proceedings, Congress doesn’t have the right to the information, said people familiar with the discussions.
“Well, we’ll be issuing a letter," President Donald Trump told reporters as he departed the White House Friday. Asked whether he was going to cooperate with any House subpoenas, Trump was noncommittal.
"I don't know, that's up to the lawyers," he said. "I know the lawyers think they've never seen anything so unfair, never seen anything so unjust."
Trump had said Thursday he would leave the decision up to the lawyers on whether to cooperate with the congressional investigation into whether he used the power of his office to pressure Ukraine to investigate 2020 rival Joe Biden.
