First thing had to do was add a line to the /etc/sudoers file. I used
add this line to /etc/sudoers
# Users in the truecrypt group are allowed to run TrueCrypt as root. %truecrypt ALL=(root) NOPASSWD:/usr/bin/truecrypt
Then I added a group called truecrypt
$sudo addgroup truecrypt
than I added myself to the group
$sudo usermod -a -G truecrypt username
After this was done I did a reboot to get it work.
