Aides for President Trump have compiled folders to keep track of attacks Republican lawmakers and others levy against the president, The Washington Post reported Wednesday.

The newspaper reported that aides have documented criticisms made by Sen. Bob Corker (R-Tenn.) and other detractors about the president.

In Corker's case, they reportedly used the remarks to remind Trump of the senator's past comments and convince him not to fully support Corker if he were to re-enter this year's midterm race.

Aides reportedly reminded the president of the remarks to make sure he would not back the senator if he changed his mind. They said they did not want the feud brought back to the public's attention, according to the Post.

Some Republicans reportedly told Corker that he would not be able to win the seat without Trump's backing.

Corker announced last fall that he would not seek reelection to the Senate this year. However, amid calls from constituents, he briefly reconsidered his decision before announcing Tuesday he will not seek another term.

Corker sparred with President Trump in the weeks that followed his retirement announcement last September. He said the president is not a good role model and would be remembered for "debasing" the nation.

Trump lashed out at Corker in response, labeling him "liddle' Bob" and suggesting he "couldn't get elected dog catcher."

The relationship between the two has since cooled.

Sen. Jeff Flake (R-Ariz.), who is also retiring at the end of his current term, has also frequently spoken out against Trump's rhetoric. The president has targeted the senator a number of times on Twitter in response.

Former White House aide Omarosa Manigault-Newman received widespread attention when she said leading up to the 2016 election that "Every critic, every detractor, will have to bow down to President Trump."
