The invitation reads: Jim Clyburn's World Famous Fish Fry.

World famous?

"Well, it's my world," Majority Whip James Clyburn said, chuckling. "And anybody else who would like to claim space in it." When it comes to South Carolina Democratic politics, it's hard to argue. Clyburn, at 78 years old, is the most influential Democrat in the state, which explains why most of the 2020 Democratic presidential field is headed to Columbia, S.C., next Friday for a chance to appear by his side.

Maybe you know colleagues who keep a sweater or a blanket at their desks to stay warm as the air conditioning tries to ice them out. Alternatively, maybe you have a co-worker who always comments on how warm the space is.

Either way, it's evident that the battle for the thermostat is being waged in offices and homes across the United States.

It's the debate that Tom Chang and his wife have been having for more than a decade.

Rep. Liz Cheney does not mince words, but when it comes to her own political ambitions, the Wyoming Republican has nothing to say right now.

"I don't have any announcements to make about that," a tight-lipped Cheney told reporters at a recent press conference dominated by questions about her political future.

House Speaker Nancy Pelosi will convene a meeting Wednesday morning to hear from Democrats on whether to move forward with impeachment proceedings against President Trump.

Pelosi, a public skeptic of impeachment, is confronting a rising tide of support for it among rank-and-file House Democrats and members of her own leadership team. Democrats are outraged by the Trump administration's ongoing effort to stymie congressional oversight into the president, his administration, and the findings in special counsel Robert Mueller's report.

More than a decade ago, then-Speaker Nancy Pelosi declared victory over the Bush administration in a clash between Congress and the president's assertion of executive privilege to try to block members of his administration from testifying as part of a congressional oversight investigation.

"It's a triumph for the balance of power, checks and balances, the Constitution of the United States," Pelosi said in March 2009.

If House Democrats ultimately begin impeachment proceedings against President Trump, last week will be remembered as one of the pivotal turning points.

Trump's decision to invoke executive privilege over the full report by special counsel Robert Mueller is prompting impeachment skeptics like Rep. Emanuel Cleaver, D-Mo., to reconsider.

Attorney General William Barr's refusal to appear before the House Judiciary Committee did accomplish one thing, according to Rep. Jamie Raskin, D-Md.

"They have succeeded in building a near unanimous sense in the Democratic Caucus that the executive branch of government is in defiance of the Constitution and the rule of law," said Raskin, a former constitutional law professor who sits on both the House Judiciary and Oversight committees.
