CharacterController.Move Not Corresponding to gameobject.transform.rotation

Question

I'm trying to create my own FPS controller and I'm using CharacterController.Move() to move. However it isn't corresponding to the gameobject's transform.rotation like I was expecting since I've assigned the gameobject's transform.rotation = Quaternion.Euler(rot). The characterController moves but only along Input.GetAxis("Horizontal") and Input.GetAxis("Vertical"). Does CharacterController.Move() operate independently from a gameobject's transform.rotation? That's what I think is happening. How would I be able to get the CharacterController to move while also following the gameobject's transform.rotation?

 using UnityEngine;
 using System.Collections;
 
 public class FirstPersonController : MonoBehaviour {
     
     public Vector2 rot;
     public Vector3 movement;
     
     public float movementSpeed = 5.0f;
     public float mouseSensitivity = 5.0f;
     public float jumpAmount = 5.0f;
     
     public float clampAngle = 90.0f;
     
     public CharacterController characterController;
     
     // Update is called once per frame
     void Update () {
         // Rotation
         rot.y += Input.GetAxis("Mouse X") * mouseSensitivity;
         rot.x += -Input.GetAxis("Mouse Y") * mouseSensitivity;
         rot.x = Mathf.Clamp(rot.x, -clampAngle, clampAngle);
         transform.rotation = Quaternion.Euler(rot);
         
         movement.y += Physics.gravity.y * Time.deltaTime;
         
         if( characterController.isGrounded && Input.GetButton("Jump") ) {
             movement.y = jumpAmount;
         }
         
         movement = new Vector3(Input.GetAxis("Horizontal") * movementSpeed, movement.y, Input.GetAxis("Vertical") * movementSpeed);
         
         characterController.Move(movement * Time.deltaTime );
     }
 }

The .Move() method takes absolute movement, so you need to rotate the input by your transform's rotation before attempting to move.

          movement = movement * transform.rotation;
          characterController.Move(movement * Time.deltaTime );

Okay so now my character is moving backwards on it's own without any keyboard input. I assume this is due to characterController.Move now including transform.rotation for it's values along with keyboard inputs. How do I include only the keyboard inputs for movement but also have characterController.Move correspond with the gameobject's transform.rotation?

         movement = transform.rotation * movement;
         characterController.Move(movement * Time.deltaTime );

edit:

 if (movement.magnatude != Vector3.zero)
 {
   movemovement = transform.rotation * movement;
   characterController.Move(movement * Time.deltaTime );
 }

The charactercontroller is still moving with the mouse.

          if (movement.magnitude != 0)
          {
            movement = transform.rotation * movement;
            characterController.Move(movement * Time.deltaTime);
          }
