A tweet knocking President Barack Obama’s and Hillary Clinton’s “failed” policies after three potential terror attacks over the weekend was deleted from Donald Trump’s account on Monday.

The notoriously tweet-happy GOP nominee’s reasons for deleting the tweet after posting it Sunday night were unclear.

Over the weekend, an explosive injured 29 in Manhattan, other devices were discovered in Seaside Park and Elizabeth, New Jersey, and nine people were stabbed in an attack in St. Cloud, Minnesota.

In a Monday statement, the Trump campaign accused the Obama administration of “diminishing the threat” posed by the Islamic State and blamed Clinton for backing the White House’s “failed ISIS strategy to the hilt.”
