After President-elect Trump announced that Elon Musk and Vivek Ramaswamy will lead the Department of Government Efficiency, an effort to root out government waste, Sen. Elizabeth Warren, D-Mass., criticized Trump's decision, suggesting he had tapped two people to execute the job of one person.

"The Office of Government Efficiency is off to a great start with split leadership: two people to do the work of one person," Warren said in a post on X, sarcastically adding, "Yeah, this seems REALLY efficient." 

Musk and Ramaswamy "will pave the way for my Administration to dismantle Government Bureaucracy, slash excess regulations, cut wasteful expenditures, and restructure Federal Agencies," Trump said in a statement.

Trump noted that the team, nicknamed "DOGE," "will provide advice and guidance from outside of government, and will partner with the White House and Office of Management & Budget to drive large scale structural reform, and create an entrepreneurial approach to Government never seen before."

Musk has invited the public to share their thoughts about what should and should not be slashed.

"All actions of the Department of Government Efficiency will be posted online for maximum transparency. Anytime the public thinks we are cutting something important or not cutting something wasteful, just let us know! We will also have a leaderboard for the most insanely dumb spending of your tax dollars. This will be both extremely tragic and extremely entertaining," he tweeted.

Ramaswamy dropped his bid for the GOP presidential nomination and endorsed Trump back in January.

"DOGE will soon begin crowdsourcing examples of government waste, fraud, & and abuse. Americans voted for drastic government reform & they deserve to be part of fixing it," he tweeted.

Warren also criticized Trump's decision to tap Pete Hegseth for Defense secretary, claiming that he is not qualified for the role.

"A Fox & Friends weekend co-host is not qualified to be the Secretary of Defense. I lead the Senate military personnel panel. All three of my brothers served in uniform. I respect every one of our servicemembers. Donald Trump’s pick will make us less safe and must be rejected," she declared in a post on X.

Hegseth is an author and Army veteran who earned two Bronze Stars and a Combat Infantryman's Badge, according to his website.

His last day with Fox was Tuesday.

Trump said in a statement that Hegseth "will be a courageous and patriotic champion of our ‘Peace through Strength’ policy."
