Actually, everyone should. First, that they think $1,400 duffle bag is okay. Translate that to government spending with someone else's money. Second, more likely he lied and it is his bag. Again, this says he thinks it is okay to lie. That is equally bad issue.
Someone should ask, who is the staffer that has a $1,400 bag. Can they prove legit source? Receipt, etc.
Confirmed bad spender or liar, should resign. Party owns this.
