In 2016 the Trump campaign solicited foreign aid from other countries besides Russia. It was reported at the time.and confirmed by the people he solicited. I wonder why nobody has mentioned it as a pattern considering the current impeachment discussions.
In 2016, Trump and his sons e-mailed British members of parliament soliciting aid for his US election campaign.
They targeted UK MP's who supported Brexit on the assumption that they shared a common view of governance with Trump. They also sent solicitation e-mails to elected representatives in Canada, Australia, and Iceland according to a BBC article.

Recipients considered it bizarre and rejected the solicitations. Even the Brits knew it was against US law.
The act of solicitation was illegal, even though it was rejected.
