Donald Trump quoted a tweet that was meant for his daughter to another person named Ivanka. The person he accidentally retweeted then used her "15 minutes of fame" to tweet about global climate change and her frustration with Donald and the Republican Party for ignoring it.
Ivanka Trump, Donald Trump's daughter, sat in on a private meeting between the President-elect and Japanese Prime Minister Shinzo Abe while her husband sat in the background. Her participation can be seen as a conflict of interest for Donald Trump because Ivanka and her brother will be running his businesses while he is President. **Update** The New York Times reported that Ivanka is in the process of finalizing a business deal with a Japanese clothing manufacturer Sanei International whose largest shareholder is the state owned Development Bank of Japan .
Ivanka Trump, Donald Trump's daughter, participated in a phone call between Donald Trump and Argentine President Mauricio Macri shortly after his electoral victory. Her participation in the conversation raise conflict of interest questions considering Trump has multiple business ventures in Argentina and she will be running her fathers business empire while he is President.
