Fred Wertheimer, 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."
Campaign finance law prohibits campaigns from knowingly accepting or soliciting contributions from foreign nationals. It's not clear whether the Trump campaign purposefully sent the emails to foreign members of parliament.
The complaint from the two watchdog groups notes that elected officials in Iceland, Scotland, Britain and Australia have received the emails.
Members of parliament in Denmark and Finland also say they have received the fundraising pleas.
