This phrase may be one key
to President Trump’s conflict of interest predicament.
He should consider transactions with his companies,
or with his siblings,
at arm’s length,
meaning to say that no undue
personal consideration is being afforded
his siblings or his companies.
After all, a conflict of interest may be brought up
if there is suspicion that transactions
were influenced by personal considerations.
When dealing at arm’s length
the transactions are purely business in nature.
