(CNN) President Donald Trump issued the second veto of his presidency Tuesday, stopping a congressional resolution that would have sought to end US involvement in the Saudi-led war in Yemen.

"This resolution is an unnecessary, dangerous attempt to weaken my constitutional authorities, endangering the lives of American citizens and brave service members, both today and in the future," Trump wrote to the Senate Tuesday.

Trump added that the resolution is "unnecessary" in part because there are no United States military personnel in Yemen "commanding, participating in, or accompanying military forces of the Saudi-led coalition against the Houthis in hostilities in or affecting Yemen."

Trump was expected to issue the veto as the resolution was seen as a rebuke of Trump's Middle East policies.
