NEW YORK >> President Donald Trump is about to become a grandfather for a ninth time.

Trump’s son Eric announced on Twitter today that he and his wife Lara are expecting their first child.

The baby boy is due in September.

Eric Trump, who lives in New York, wrote “it’s been an amazing year” and said that he and his wife were “blessed” by the pregnancy.

The president retweeted his son’s post on Monday, adding, “Congratulations Eric & Lara. Very proud and happy for the two of you!”
