Powershell - How to remove confirmation window from script

Hi EE

I have the script below that removes the users from the listed groups .. but it is prompting me to confirm for each user .. how can I remove that ? or any way to make this better ?

I basically need to remove a set of users from the groups in groups.tst

Foreach ($User in GC e:\Projects\Groups\Users2.txt){
GC e:\Projects\groups\groups2.txt | % {
Remove-ADGroupmember -identity $_ -member $User
      }
}
