Nancy Pelosi now exploring impeachment against President Trump amid Ukraine controversy

After months of holding back, House Speaker Nancy Pelosi is now exploring whether the time has come for Democrats to impeach President Donald Trump.

Pelosi has spent the last several days "sounding out" impeachment, the Washington Post reported. She was actively busy Monday night gauging support in her Democratic caucus as to whether the House should proceed with the move.

The California Democrat is scheduled to meet with six House committee chairmen Tuesday to further discuss how they should proceed, CNN reported. The Constitution mandates that the House initiates impeachment proceedings.

According to the Post, Democratic aides believe Trump's impeachment is now "inevitable" whereas it was previously "unlikely."

Indeed, the development is a significant turn of events.

Just earlier this month, Pelosi scolded her party for continuing to push impeachment, which she called a "divisive measure." Instead, she urged her party to retreat from impeachment and engage in facts.

However, the tipping point came last week when new controversy enveloped Trump, stemming from a July conversation he had with Ukrainian President Volodymyr Zelensky. During that conversation, Trump allegedly pressured Ukraine to investigate former Vice President Joe Biden's son, Hunter Biden, although Ukraine denied Trump pressured their president.

On Monday, Trump seemingly admitted to pressuring Zelensky. He told reporters that he threatened to withhold $250 million in military aid if Ukraine did not crack down on corruption. The president's detractors characterized the comments as a reference to the alleged corruption of Hunter Biden.

Pelosi's impeachment exploration comes after Rep. Alexandria Ocasio-Cortez (D-N.Y.) excoriated the Democratic Party over the weekend for inaction against Trump, which she called a "bigger national scandal" than Trump's "lawbreaking behavior."
