A report from the CNN
United States House Democrats are speeding up impeachment proceedings against Donald Trump to avoid court battles that could delay the inquiry.
They want less witnesses at public hearings.
Long serving career diplomat William Taylor told lawmakers it was "his clear understanding that US security aid was being withheld from the Ukraine until Ukraine did for President Trump what would amount to political favours."
It has been reported that President Trump could be impeached as soon as next month.
