Trump's term has seen a record number of fired or resigned officials, but there are six people who have remained steadfast for the past four years.

Attorney General William Barr becomes the 12th member of President Donald Trump's cabinet to resign or be fired during his four-year term.

Only six officials in the Trump cabinet can hold on from the beginning of the term to the present, including Treasury Secretary Steven Mnuchin, Agriculture Secretary Sonny Perdue, Commerce Secretary Wilbur Ross, Minister

The six officials who "survived" Trump's tenure have little in common.

However, they all have to try to complete the most difficult task in a chaotic administration: avoiding the anger of Trump.

The finance minister is often a close ally to the president.

Particularly loyal to Trump, Mnuchin did not change his stance while working at the Treasury Department and avoided becoming the focus of attention.

One of Mnuchin's achievements was the 2017 tax law, in which he contributed to drafting and defending in parliament.

Mnuchin also drew criticism from some Republicans when negotiating the first round with Democrats on the economic bailout package related to the Covid-19 pandemic.

Sonny Perdue joins Trump's cabinet as Agriculture Secretary.

At the Department of Agriculture, Perdue's work is often overlooked, but he's a "silent force" in the Trump administration.

Perdue also often openly admits the harm American farmers have suffered from the tariffs that punish China.

Perdue is seen as a "bridge" for the relationship between Trump and American farmers, contributing to increasing the rate of support of the US President in most rural areas in the 2020 election.

More than any other minister in the cabinet, Commerce Secretary Wilbur Ross was the most reliable supporter of Trump's trade protectionist policies.

At the Commerce Department, Ross has always implemented tariff measures and other protective activities, which have contributed to defuse Trump's outrage with his poor TV performances.

It was Ross who recommended that Trump use his national security authority to impose aluminum and steel taxes on China and then on allies in North America and Europe.

Trump frequently says that he wanted to fire Ross in the fall of 2019, but decided to keep the Secretary of Commerce because both acquaintances had long and had much in common, and he couldn't fire his old friend

HUD Secretary of Housing and Urban Development (HUD) Ben Carson joins the Trump cabinet and US politics as a "newcomer", as he previously worked as a neurosurgeon.

Under the leadership of Carson, the agency faced a series of minor scandals and investigation.

During his incumbent period, the relationship between Carson and Trump was relatively calm because Trump was not too concerned with the issues of the ministry.

Carson in the fall was also infected with nCoV and said he was "very sick" before recovering.

Unlike the President and many other cabinet members, Transportation Secretary Elaine Chao is not "non-Washington".

Ms. Chao is the wife of Senate Majority Leader Mitch McConnell.

In 2017, after McConnell and several other Republican leaders criticized Trump's reaction to the Charlottesville protests, the President publicly criticized him.

This loyalty, combined with the lack of "interest" in Trump's federal traffic policies, has helped her run a relatively pleasant term.

Coming from a wealthy Michigan family, Betsy DeVos went from a major Republican donor to US Secretary of Education.

Although DeVos has also repeatedly disapproved of Trump and has faced harsh criticism from the White House boss, she has so far preserved her position in the President's cabinet.
