Second whistleblower emerges in Trump-Ukraine scandal

A second whistleblower has come forward with first-hand knowledge of President Donald Trump's attempts to get the Ukrainian president to investigate a political rival, lawyers for the official said on Sunday.

Lawyer Mark Zaid said the person, also an intelligence official, has direct knowledge of some of the allegations involving the initial whistleblower complaint, which triggered impeachment proceedings against the Republican president.

The emergence of a second protected witness complicates efforts by Trump and his Republican supporters to dismiss the complaint as politically motivated hearsay and may strengthen the Democrats' case against him.
