Democrats see it much differently - and are demanding answers.
"It's time for the Trump Administration to come clean," said Sen. Chris Coons (D-DE).
"The administration needs to stop stonewalling and turn over the whistleblower complaint now, as required by law," said Rep. Diana DeGette (D-CO).
"If they refuse, President Trump should be impeached immediately," DeGette added.
Under federal law, the complaint from the unidentified whistleblower should have already been turned over to the House and Senate Intelligence Committees - but the Acting Director of National Intelligence has failed to do that.
Current law does include the possibility where the whistleblower could go directly to the Congress with the information.
Most Republicans in Congress have said little about the latest Trump controversy; one of the few was Sen. Mitt Romney (R-UT).
"If the President asked or pressured Ukraine’s president to investigate his political rival, either directly or through his personal attorney, it would be troubling in the extreme," Romney wrote on Twitter.
