WASHINGTON (AP) — The White House is pushing back against criticism it lacks a coordinated effort to fight House Democrats’ impeachment inquiry and could do a better job delivering its message. White House spokeswoman Stephanie Grisham told Fox News Channel on Thursday it’s difficult “to message anything that’s going on behind closed doors” and it’s like “fighting a ghost.” The House impeachment inquiry is examining whether President Donald Trump withheld military aid to pressure Ukraine to investigate Joe Biden.
