The law gets very interesting when the call is across state lines.
Your comment that the law in the state where it was recorded prevails is not necessarily true. See the case I posted sbove.
...and where was Trump at the time? In FLA? In DC? Elsewhere?
Can you record a call from another state?
Recording conversations between states
Generally speaking, laws favor the state where the call originated from. In this case, only one-party consent is needed because the call is coming from Texas. If the call originated in Florida, two-party consent would be needed.
Ratsburger appears to have broken the law as Trump called him.
DC Wiretapping Law
The District of Columbia’s wiretapping law is a “one-party consent” law. DC makes it a crime to record a phone call or conversation unless one party to the conversation consents. See D.C. Code § 23-542. Thus, if you operate in DC, you may record a conversation or phone call if you are a party to the conversation or you get permission from one party to the conversation in advance. That said, if you intend to record conversations involving people located in more than one state, you should play it safe and get the consent of all parties.
In addition to subjecting you to criminal prosecution, violating the DC wiretapping law can expose you to a civil lawsuit for damages by an injured party.
Consult The Reporters Committee for Freedom of the Press’s Can We Tape?: District of Columbia for more information on DC wiretapping law.
My take is that any party recording in a state where 2 party consent is required by law is in violation if they do not disclose said recording to the other party regardless of what state/state laws are there.
