Trump has spent a chunk of his December vacation at his Mar-a-Lago resort in Florida complaining about Pelosi's decision to withhold the two articles of impeachment from the Senate until after lawmakers return from recess.

"They produced no case so now she doesn’t want to go to the Senate. She’s all lies. Most overrated person I know!" Trump tweeted Tuesday.

Remember when Pelosi was screaming that President Trump is a danger to our nation and we must move quickly. They didn’t get one Republican House vote, and lost 3 Dems. They produced no case so now she doesn’t want to go to the Senate. She’s all lies. Most overrated person I know! — Donald J. Trump (@realDonaldTrump) December 31, 2019

The House voted earlier this month to impeach Trump for abuse of power and obstruction of Congress following an investigation into his conduct toward Ukraine. Democrats alleged the president made security assistance and a White House meeting for Ukraine contingent on the country announcing investigations into Trump's rivals.

McConnell and other senators have indicated they would rather not call witnesses in hopes of a quick trial that ends in Trump's acquittal. But leading Democrats have pushed for administration officials to testify as part of any Senate proceeding.

The Speaker's decision to hold onto the articles has proven to be a sticking point for Trump, who has tweeted more than a dozen times about Pelosi since arriving at his West Palm Beach property.
