Nancy Pelosi launches formal impeachment inquiry against Donald Trump amid reports he withheld aid money from Ukraine - as he brands the move 'more breaking news Witch Hunt garbage' and accuses the Dems of 'presidential harassment'

House Speaker Nancy Pelosi on Tuesday launched a formal impeachment inquiry into Donald Trump, giving into demands from her party's leading presidential candidate and her top lieutenants that Congress attempt to oust the sitting president.

Pelosi announced in a televised statement that she'd opened an umbrella for numerous congressional investigations into the Republican president who Democrats say is in willful violation of the U.S. Constitution.

'This week the president has admitted to asking the president of Ukraine to take actions which would benefit him politically. The actions of the Trump presidency revealed dishonorable fact [sic] of the president's betrayal of his Oath of Office, betrayal of our national security, and betrayal of the integrity of our national elections,' she said in a 5 pm announcement.

'Therefore, today I'm announcing the House of Representatives is moving forward with an official impeachment inquiry. I'm directing our six committees to proceed with their investigation under that umbrella of impeachment inquiry. The president must be held accountable. No one is above the law.'
