“The Director of OMB is responsible for overseeing the development and implementation of the federal budget and plays a significant role in any Administration’s fiscal and regulatory agenda. Congress has to be able to trust the OMB director to make countless decisions in an impartial manner, carrying out the letter of the law and congressional intent," Collins said in a statement first obtained by Politico.
"Neera Tanden has neither the experience nor the temperament to lead this critical agency. Her past actions have demonstrated exactly the kind of animosity that President Biden has pledged to transcend,” Collins added.
The senator also said Tanden’s "decision to delete more than a thousand tweets in the days before her nomination was announced raises concerns about her commitment to transparency.”
“Should Congress need to review documents or actions taken by OMB, we must have confidence that the Director will be forthcoming,” Collins said, adding that the office “needs steady, experienced, responsive leadership.”

The West Virginia senator on Friday pointed to Tanden's harsh tweets about Republicans as the reason for his opposition.
"I believe her overtly partisan statements will have a toxic and detrimental impact on the important working relationship between members of Congress and the next director of the Office of Management and Budget," Manchin said in a statement. "For this reason, I cannot support her nomination."
Republicans in two confirmation hearings last week skewered Tanden, who built a reputation for partisan warfare on Twitter as the head of the Center for American Progress, for a number of previous tweets, many of which she recently deleted.
She has repeatedly apologized for the tweets, some of which compared Republicans to evil fictional characters.
Most Republicans were expected to oppose Tanden over her rhetoric, and it may be difficult for a GOP senator to back her now that Biden needs at least one of them to support her to get her confirmed.
Following the news of Collins's opposition on Monday, the White House tweeted in support of the OMB nominee, saying that Tanden is "an accomplished policy expert."
