Michigan state legislature closes offices due to 'credible threats of violence'

Retired four-star Gen. Lloyd Austin could have a bumpy path to nomination as Biden’s defense secretary -- and not necessarily because of GOP opposition, but rather, opposition from Democrats. 

While some praise his qualifications, they are against waiving the requirement that military brass be at least seven years post-retirement for that position. Others have said they are open supporting the nomination.

Senate Minority Leader Chuck Schumer on Wednesday said he's going to have to "study" the waiver in this case.

"Bottom line is that Austin's a very good nominee, and we'll figure out where to go from there," Schumer told reporters. "I haven't talked to my colleagues yet about that I want to see what they have to say."

Sen. Jack Reed, the top Democrat on the Senate Armed Services Committee, signaled he's open to the waiver in a statement Wednesday despite previously saying he wouldn’t consider one again after voting in favor of the waiver for Trump's first defense secretary, retired Gen. James Mattis.

“It is the obligation of the Senate to thoroughly review this nomination in the historic context it is being presented and the impact it will have on future generations. Indeed, one cannot separate the waiver from the individual who has been nominated," the statement said. "I will carefully review this nomination and look forward to meeting with General Austin.”

But Sen. Richard Blumenthal, D-Conn., a senior member of the Armed Services Committee, has already told reporters he would not support the waiver, joining Democratic Sens. Elizabeth Warren and John Tester in expressing opposition. All three voted against granting the waiver to Mattis.

“I have the deepest respect and admiration for General Austin and this nomination. It is exciting and historic, but I believe that a waiver of the seven-year rule would contravene the basic principle that there should be civilian control over a nonpolitical military," Blumenthal said Tuesday. "I think, has to be applied unfortunately in this instance.”

House Democratic Leader Steny Hoyer told reporters Wednesday morning that he's concerned about the slim Democratic majority heading into the next session of Congress, given Biden's decision to pluck certain members for his administration.

Rep. Cedric Richmond was tapped as a senior White House adviser and Rep. Marcia Fudge as secretary of Housing and Urban Development, according to sources.

Hoyer said he told Biden's team to be "very careful" in terms of who it selects to join the team. Democrats are breathing easier knowing that Richmond and Fudge's respective seats are relatively safe Democratic seats -- but special elections take time, so the margins in the House will be incredibly tight in the coming weeks and months ahead. 

"I’m certainly concerned by the slimming of the majority. I indicated to the administration very early on that I wanted them to be very careful in terms of the members that they appointed from Congress given the closeness of our majority," Hoyer said. 

"I think, frankly, we're going to be a very unified caucus, as we were this past Congress," Hoyer added. "The American people are confronting two great crises: one a health crisis and the other an economic crisis, and they expect us to come together as a Congress on their behalf."

Intra-party rumblings about diversity and experience are more than background noise as Biden builds out his governing team. The relatively drama-free transition has masked concerns about whether Biden's decisions can meet his commitments -- with implications for governance after Jan. 20.

Biden's choice of California Attorney General Xavier Becerra to lead Health and Human Services puts a Latino in a high-profile spot, though Biden's stumble over his last name wasn't the best introduction to the country.

Still, coming out of Biden's meeting with prominent Black leaders Tuesday night, some want Biden to create a new high-ranking advisory job -- and Black and Latino activists and advisers are focused on the attorney general's job as well.

The choice of Austin is also leaving Democrats worried about preserving civilian control over the Defense Department. For some, that will mean explaining why a Trump appointment of a recently retired general shouldn't have gotten a legal waiver to serve in the role, while a Biden one should.

Just last week, Biden re-set his high bar: "I promise you, it'll be the single most diverse Cabinet based on race, color, based on gender, that's ever existed in the United States of America," he told reporters.

He is making picks that move him in that direction. But the unity Democrats have found in opposing the Trump White House is showing signs of strain as names roll out -- to say nothing of policy.

Trump has vowed to intervene in a long-shot lawsuit filed by the state of Texas directly to the Supreme Court  Tuesday seeking to toss out ballots in four states where Biden won as he continues his campaign to overturn the results of the presidential election.

“We will be INTERVENING in the Texas (plus many other states) case. This is the big one. Our Country needs a victory!” Trump tweeted Wednesday morning. 

The state of Texas filed a lawsuit Tuesday against Michigan, Wisconsin, Pennsylvania and Georgia, arguing that those states “exploited the COVID-19 pandemic to justify ignoring federal and state election laws and unlawfully enacting last-minute changes, thus skewing the results of the 2020 General Election.” 

Justices have not said whether they'll weigh the case, but legal experts say it's is unlikely to succeed. 

Trump provided no details on how he would intervene.

The tweet comes after the Supreme Court on Tuesday denied a request from Trump allies to stop the certification of Pennsylvania's election results -- a case Trump said had "nothing to do with him" on Wednesday.

Notably, before the Supreme Court's denial came in, Trump called on the justices to have the "courage" to intervene at an event on coronavirus vaccines at the White House.

"Now, let's see whether or not somebody has the courage -- whether it’s a legislator or legislatures, or whether it's a justice of the Supreme Court or a number of justices of the Supreme Court. Let's see if they have the courage to do what everybody in this country knows is right," he said Tuesday.
