Yesterday it emerged that Donald Trump has been — bizarrely — sending fundraising emails to foreign citizens, including members of parliament in the UK, Australia, Iceland, Denmark and Finland.

Today, two watchdog groups have announced they’re filing FEC complaints alleging that the Trump campaign has broken federal law.

“Donald Trump should have known better,” Paul S. Ryan, the deputy executive director at the Campaign Legal Center, said in a statement. “It is a no-brainer that it violates the law to send fundraising emails to members of a foreign government on their official foreign government email accounts, and yet, that’s exactly what Trump has done repeatedly.”

Fred Werthemier, the president of Democracy 21, said that Trump’s fundraising pleas to foreign members of parliament are “a strange and unique development that we have not seen before in campaign fundraising.”
