House Democrat details reasons for voting "no" on COVID-19 relief bill

Rep. Jared Golden, one of only two House Democrats who voted against the COVID-19 bill early Saturday, detailed his decision to vote no in a lengthy statement, taking issue with the size and scope of the package -- and the large price tag that comes with it.

Golden said he supported funding for vaccine distribution and testing, and emergency unemployment benefits, but disagreed with the funding efforts that duplicate efforts still being funded by previous stimulus plans or that he views as unnecessary -- including the income range for the $1400 Direct Checks

"This bill allocates $1,400 direct checks to individuals making up to $75,000 and married couples making up to $150,000, with phased-down checks for households with incomes as high as $200,000. Under this bill, it is estimated that over 90 percent of Maine tax filers would receive a check from the federal government. While those who have lost jobs or had hours reduced ought to receive income support, it is a waste to send a third round of government checks to wealthy individuals making almost three times the average household salary in Maine’s Second Congressional District," he wrote.

Golden also took issue with the inclusion of the Child Tax Credit expansion, a two-year enhancement of premium subsidies under the Affordable Care Act, and multiemployer pension reform, saying he supported the policy but disagreed with passing them through an emergency bill.

“Many have popularly claimed that the biggest threat is not that Congress goes too big but that it goes too small in responding to the current economic situation," Golden wrote, paraphrasing Biden's common talking point.

"They are ignoring the possibility of a much-anticipated infrastructure proposal from the Biden Administration later this year which could offer a chance for Congress to further boost the economy if necessary. Between the money spent in 2020 and today’s package, we are already nearing $6 trillion in new spending in less than one year. This amount of new spending is unprecedented since World War II. It’s not unreasonable to take a step back and ask ourselves if we are making every dollar count and picking the right priorities. At some point, the bill has to come due, and when it does, it could put at risk critical programs such as Medicare or sap resources needed for important future priorities, from rebuilding our crumbling infrastructure to fixing our broken healthcare system.”

Notably, nowhere in the statement is the issue of the $15 minimum wage mentioned.

Harris celebrated Black History month on Saturday in a keynote address at the 40th Annual Black History Month virtual celebration.

In her speech, she applauded the House for passing a $1.9 trillion COVID-19 relief package and touted how the bill would lead to $1,400 direct payments for Americans, a child tax credit and $20 billion toward a national COVID-19 vaccination program.

She said she plans to get the bill “across the finish line.”

She cited how the Black community has been hard hit in the pandemic.

“We are looking at a country in a situation where more than two in three Black Americans personally know someone who has been hospitalized or who has died from COVID-19,” she said.

“Black women workers are being forced out of the workforce in record numbers, and so many Black small businesses are being forced to close their doors,” Harris added.

“In so many ways, this pandemic has been an accelerator. And for those for whom things were bad before, they're even worse now for the fissures and the failures, the defects, the flaws in our system, during the course of this pandemic, have been blown up for all to see,” she said.

She celebrated the “the barrier breakers and the history makers” who came before her.

“I think of history in the context of a relay race. With each generation running their course and passing the baton to the next. And so, the baton is now in our hands and what matters is how well we run our portion of the race,” Harris said.

During brief remarks Saturday morning, Biden praised the House passage of his American Rescue Plan and urged the Senate to pass the bill, warning there’s “no time to waste.”

He said he spoke with House Speaker Nancy Pelosi just before stepping out and thanked her for her work on the effort and for moving the country “one step forward” on relief.

The $1.9 trillion economic coronavirus relief package will provide resources to schools and businesses, boost funding for vaccinations and testing and grant financial relief to Americans across the country.

“With their vote, we're one step closer to vaccinating the nation. We are one step closer to putting $1,400 in the pockets of Americans,” Biden said. “We're one step closer to extending unemployment benefits for millions of Americans who are shortly going to lose them. We're one step closer to helping millions of Americans feed their families, and keep a roof over their head.”

“We're one step closer to getting our kids safely back in school. And we're one step closer to getting state and local governments the money they need to prevent massive layoffs for essential workers,” he added.

He directed a message to the Senate stressing, “I hope it will receive quick action.”

“If we act now, decisively, quickly and boldly, we can finally get ahead of this virus, we can finally get our economy moving again, and the people of this country have suffered far too much for too long.”

Garland described the Jan. 6 insurrection at the Capitol as "the most heinous attack on the democratic processes I have ever seen and one I never expected to see in my lifetime." He added he will make sure to provide career prosecutors all the resources they need to carry out their investigations while also taking a broader look at the symptoms behind the country's domestic extremism problem.

Asked by Sen. Dianne Feinstein, D-Calif., whether the president "has the absolute right to do what he wants with the Justice Department," Garland said presidents are "constrained by the Constitution as are all government officials" and cited comments by Biden committing to not interfere with Justice Department matters. At the same time, Garland said that the Department of Justice is part of the executive branch and because of that, on policy matters they do "follow the lead of the president and the administration as long as it is consistent with the law." When asked who an attorney general represents when his interests conflict with the president's, Garland said the attorney general "represents the public interest, particularly and specifically as defined by the Constitution and the statutes of the United States."

Asked whether the president can order an attorney general to open or close an investigation, Garland said such a question was a hard one for constitutional law but that he did not expect it to be a question for himself given President Biden's statements assuring independence for the department.

Sen. Lindsey Graham, R-S.C., took a contentious tone with Garland in his line of questioning as he pressed him on multiple topics. At one point, when Graham asked Garland whether he thought former FBI Director Comey was a good FBI director, Garland declined to answer, which Graham said he found "stunning" because he thought Comey was terrible. Sen. Sheldon Whitehouse, D-R.I., pressed Garland on whether he would commit to investigating not only the rioters who attacked the Capitol on Jan. 6, but those "upstream" like the funders, organizers, ringleaders or others not actually at the Capitol.  Garland cited his past experience as a line prosecutor, noting "we begin with the people on the ground and we work our way up to those who are involved and further involved -- and we will pursue these leads wherever they take us."

Asked about whether he would end the Trump Justice Department's policy of generally stonewalling in the face of oversight requests from Congress, Garland committed to Whitehouse that the department would be "as responsive as possible" to any requests and "at the very least why if it can't answer a question or can't answer a letter." Garland also committed that he would work with Whitehouse on getting answers to the committee on requests that the Justice Department under Attorneys General Bill Barr and Jeff Sessions previously ignored.

In an exchange with Sen. John Cornyn, R-Texas, Garland committed that his personal politics will have no impact on prosecutions and investigations he oversees as attorney general. Asked what he would do if he was ordered to do something that he considered to be unlawful, Garland said he would first tell the president or whoever else was asking him that what they were ordering was unlawful and would resign if no alternative was accepted.

Asked by Sen. Amy Klobuchar, D-Minn., what he will do to improve morale in the department, Garland said he would on his first day make an oath to career prosecutors and agents "that my job is to protect them from partisan or other improper motives." Klobuchar then asked Garland whether he believes he'd need "additional authorities" to combat the country's domestic terrorism problem. Garland said while the department "is probably always looking for new tools ... the first thing we have to do is figure out whether the tools that we have are sufficient."
