expect script for getting output for multiple servers

I am trying to get output of IQN from multiple servers. I am getting the below error.

Error output

spawn /usr/bin/ssh VM2 | /usr/bin/cat /etc/iscsi/initiatorname.iscsi
root@VM2's password:
bash: -c: line 0: syntax error near unexpected token `|'
bash: -c: line 0: `| /usr/bin/cat /etc/iscsi/initiatorname.iscsi'

script

#!/bin/bash

HOSTS="VM2 VM3 VM4 VM1"

read -p "Password: " PASSWORD

for HOST in $HOSTS
do
expect -c "
spawn cat /etc/iscsi/initiatorname.iscsi
    expect {
    "*password:*" { send $PASSWORD\r;interact }
    }
    exit
    "
done

Am I doing something wrong?
