Use of "as": Am I understanding correctly?

My interpretation: In addition to Mr Trump, Republican leaders who supported him also have done harm. Am I interpreting the sentence correctly?

If the above interpretation is correct, then the following sentence is fine, right?

He stole money from the bank, as did his friend who accompanied him.
