If Trump truly has a mandate, why is he bypassing the constitution?

Trump won the election. Trump’s party holds majorities in both chambers of Congress. He can use his legitimate constitutional authority to accomplish his goals. However, with the help of Elon Musk, he is consistently violating the Constitution and willingly breaking laws to achieve his campaign promises. When will you as elected representatives to Congress, who swear an oath to the Constitution of the United States of America, perform your constitutional duty to remove Trump from office? You did not swear an oath to Donald Trump or Elon Musk. You were elected by citizens of your state to honor the constitution and represent us (the people who elected you) in Washington. What is your red line? What illegal action will be enough to spur you to perform your constitutional duty? You are obligated to protect our freedom from tyrants and want to be monarchs. We live in a representative republic that does not have concentrated power in one branch or in one person. Do your constitutional duty and impeach Donald Trump for defying the constitution.
