Trump announces new impeachment legal team

Biden, in afternoon remarks from the White House, announced that his administration has secured commitments from coronavirus vaccine makers to buy another 200 million doses to arrive this summer, raising the total to 600 million and ensuring the U.S. will eventually have two shots of the Pfizer and Moderna vaccines for nearly every American.

Biden also told the nation to expect a modest uptick in production in the near term -- from 8.6 million doses a week to a minimum of 10 million a week -- for the next three weeks.

"This is going to allow millions of more Americans to get vaccinated sooner than previously anticipated. We've got a long way to go, though," Biden said.

The announcement does not resolve the major shortages the nation is experiencing now, and does not suggest the Biden administration has found a novel way to ramp up production quickly.

One Biden administration official, who briefed reporters earlier on condition of anonymity, did not provide a firm timetable on the 200 million extra doses, pointing to the summer, but hailed the move as a guarantee that every American who wants a shot can get one.

Biden said it was enough to vaccinate 300 million Americans "by end of the summer, beginning of the fall."

The state of Texas has won a nationwide temporary restraining order against one of Biden's first executive actions as president -- a 100-day pause of immigrant deportations. 

A federal district court judge says status quo enforcement operations can continue for at least the next 14 days while both sides present their case, after which an extended injunction against the policy could be issued or the restraining order lifted.  

Biden's DHS released a "Day One" memorandum on Jan. 20 establishing a moratorium on enforcement actions against most immigrants. 

The Texas lawsuit signals the beginning of an expected wave of court challenges by Republicans targeting Biden policies after years of watching Democrats use the courts to hobble Trump's moves.

After 45 Republicans sided with his effort to dimisss the impeachment trial of former President Donald Trump for being unconstitutional, Republican Kentucky Sen. Rand Paul expressed excitement about the vote count for his failed effort.

"We're excited about it. It's one of the few times in Washington where loss is actually a victory," Paul said to reporters on Capitol Hill. "And 45 votes means that the impeachment trial is dead on arrival."

If the final vote on conviction falls at 55-45, the Senate would be 12 votes short of what is necessary to convict Trump. In order to convict Trump by the necessary two-thirds majority, at least 17 Republican senators would need to join all 50 Democrats.

Even with Tuesday's vote, there is no guarantee that the trial proceedings will not sway the votes of some senators.

Shortly after the vote, the Senate adjourned the trial until Feb. 9.

Five Republicans joined with Democrats to kill Republican Kentucky Sen. Rand Paul's effort to dismiss the upcoming impeachment trial of former President Donald Trump as unconstitutional. 

Paul's effort failed by a vote of 55-45. Sens. Mitt Romney, R-Utah, Ben Sasse, R-Neb., Pat Toomey, R-Pa., Susan Collins, R-Maine, and Lisa Murkowski, R-Alaska, voted with Democrats. 

While Paul's effort failed, many members of the Republican conference voted with Paul -- an indicator that the constitutional question for some Republicans will be an intense focus during the trial. Minority Leader Mitch McConnell was one of those to vote in favor of Paul's motion.

Majority Leader Chuck Schumer, in a speech just before the vote, said the argument that an official couldn't be tried after leaving office makes "no sense whatsoever."

"The history and precedent is clear the Senate has the power to try formal officials and the reasons for that are basic common sense," Schumer said. "It makes no sense whatsoever that president or any other official could commit a heinous crime against our country and then could evade Congress's impeachment power." 

Paul's motion comes too early, Schumer said, arguing that debate on the constitutionality question should happen during the trial.
