House Speaker Nancy Pelosi, D-Calif., announced Thursday morning that House Democrats will move ahead with drafting articles of impeachment against President Trump, though she did not define the scope of those articles.
"His wrongdoing strikes at the very heart of our Constitution," Pelosi said, referring to Trump's efforts to pressure Ukraine to investigate political rivals while hundreds of millions of dollars in military aid were on hold earlier this year.
