Thanks a lot!!! ssh-agent with ssh-add did the trick!!!
For others who are interested:
1. run ssh-agent.
2. Ensure that the correct environment variables are set
3. run ssh-add.
4. Run the original sudo command. sudo ssh*****

This is exactly what ssh-agent is designed for. In this case to set it
up you'd generate a public/private key pair for the user, put the public
key on machine 18.104.22.168, start ssh-agent on the local machine and load
the user's private key. From then on, ssh on the local machine will use
the ssh-agent to provide authentication when ssh connects to 22.214.171.124.
We use this mechanism extensively to run batch jobs across machines, and
it works great. And you don't have to do anything insecure like using
