Democrats just dropped a big hint that they have everything they need to impeach Trump - Business Insider

Democratic Rep. Adam Schiff said he viewed the White House's stonewalling and refusal to allow witnesses to comply with congressional subpoenas as potential evidence of Trump's guilt. "If this witness had something to say that would be helpful to the White House, they would want him to come and testify," Schiff said. "They plainly don't."

The California Democrat's revelation is also a big sign that Democrats believe they have enough information through other witnesses to impeach Trump over his dealings with Ukraine, particularly following damning testimony from Bill Taylor, the US's chief envoy to Ukraine, last week.

Taylor, a career diplomat and war veteran, directly implicated the president in ordering the US to freeze military aid to Ukraine unless Ukrainian President Volodymyr Zelensky acceded to his demands for political investigations into his rivals. He testified that shortly after he became the US's acting ambassador to Ukraine in June, he realized there were two channels through which US policy toward Ukraine was conducted.
