"This is about putting families above politics. And for a refreshing change, it's something we all seem to agree on. At a point when everything feels so divisive, let this be a shared goal that unites us.
"So, on behalf of my family, Archie and Lili and Harry, I thank you for considering this letter, and on behalf of all families, I ask you to ensure this consequential moment is not lost."
"No family should have to choose between earning a living and having the freedom to take care of their child (or a loved one, or themselves, as we would see with a comprehensive paid leave plan)," she says.
Republican Representative Lisa McLain spoke out to in the piece for Dailymail.com and said Meghan was interfering with politics.
"Meghan Markle is incredibly out of touch with the American people and should stick to acting instead of trying to play politics," she told the news outlet.
"The last thing we need right now is wealthy celebrities pushing their liberal agendas on the American people."
Jason Smith, another Republican Representative, spoke out with his own beliefs and made it clear he wants her royal title to be stripped.
"While her attempts at appealing to working-class families by recalling her days of eating at Sizzler were laughable, her comments make crystal clear that the passage of this massive tax-and-spend bill is aimed more at helping global elites get huge tax breaks than helping the working families she claims to have dined with," he told the Daily Mail.
A royal expert Angela Levin, a journalist and biographer of Prince Harry, claims the 1030-word letter is evidence Meghan has strong political ambitions.
"Meghan's two-page letter to lobby Congress about giving money on parental leave is obviously another step towards trying to turn herself into a politician.
"But the notepaper she is using is astonishingly 'From the Office of The Duke and Duchess of Sussex' and shows how she isn't even aware that she is talking to politicians in a republic that won its independence from the crown in 1776."
Levin certainly didn't hold back with her harsh critique of Meghan.
"The truth is that the bill about parental leave is on its way to being confirmed, and could be hijacked by Meghan's belief it was largely due to her.
"In addition if she was writing a professional letter what on Earth is she getting all cosy and intimate by stating the letter is also 'on behalf of Archie and Lili - notice she is not calling her Lillibet, the Queen's nickname - and Harry. Poor old Harry has come last."
