Trump announces new impeachment legal team

Biden continued with his calls to world leaders Monday, this time speaking with German Chancellor Angela Merkel and agreeing to revitalize the two countries alliance.

They agreed that cooperation was important to meet the challenges of the COVID-19 pandemic and climate change. They also said the U.S. and Germany would work together on foreign policy issues regarding Afghanistan, Iran, China, Russia, Ukraine and the Western Balkans.

Biden started making calls to foreign leaders on Friday, first reaching out to the leaders of Canada, Mexico and the U.K. on Friday and the French president on Sunday. COVID-19 was also a main point of conversation on those calls.

The lead House impeachment manager, Rep. Jaime Raskin, D-Md., read aloud an article of impeachment against former President Donald Trump to the Senate.

"President Trump gravely endangered the security of the United States and its institutions of government. He threatened the integrity of the democratic system, interfered with the peaceful transition of power and imperiled a coordinate branch of government. He thereby betrayed his trust as president, to the manifest injury of the people of the United States," Raskin said, reading from the article that the House passed on Jan. 13.

"Wherefore President Trump, by such conduct, has demonstrated that he will remain a threat to national security, democracy and the Constitution if allowed to remain in office, and has acted in a manner grossly incompatible with self-governance and the rule of law. President Trump thus warrants impeachment and trial, removal from office and disqualification to hold and enjoy any office of honor, trust or profit under the United States," he concluded.

Speaking after Raskin, Sen. Patrick Leahy, D-Vt., the president pro tempore, announced that the Senate was now "ready to proceed with the (impeachment) trial."

The official trial in Senate is not expected to begin until the week of Feb. 8.

House impeachment managers were delivering an article of impeachment against former President Donald Trump to the Senate Monday, queuing up a record-setting second trial for him in the chamber.

The managers, led by Rep. Jaime Raskin, D-Md., and appointed by House Speaker Nancy Pelosi, silently walked the article across the Capitol -- from the House to the Senate -- where senators awaited their arrival.

The House voted to impeach the former president on Jan. 13, a week after pro-Trump rioters stormed the Capitol in an attempt to disrupt the certification of the 2020 electoral college votes.

Despite the presentation of the article to the Senate today, the official trial is not expected to begin until the week of Feb. 8.

The Senate Monday voted to confirm Janet Yellen as secretary of the treasury, making her the first woman to lead the department in its over 230-year history.

Yellen won confirmation by a 84-15 vote as she now takes the helm of a department critical in delivering COVID-19 relief aid and managing the economy.

Appointed by former President Barack Obama, Yellen served one term as Federal Reserve chair before former President Donald Trump decided not to re-appoint her to lead the central bank. She was also the first woman to hold that position.
