No question, Melania is a beautiful woman. And her English improved over the years as FLOTUS.
Be Best!

Melania Trump is reportedly fluent in 5 languages.
Trump's children are bilingual or multilingual. They learned Czech from Ivana and Slovenian from Melania.
Whether her pronunciation of English meets anyone's standard or not is subjective. When learning to speak another language other than our native one, it's often the case that we do not pronounce words like those speaking it natively.
If we were to judge everyone by their accent, what does that say about all the Japanese, Filipino, Korean, Vietnamese, Chinese, Russian, and other immigrants who studied and are fluent in English but happen to "sound funny" when they speak English?
I'm willing to bet real money her spelling, grammar and vocabulary skills put certain forum members' English skills to shame.
