"The problems created by Trump's impulsive, erratic military action/foreign policy are again on display, this time in Iraq,” Gabbard tweeted on Tuesday afternoon.
She further described Washington’s recent strikes against the positions of Popular Mobilization Units (PMU) as “impulsive” and “short-sighted”.
“It has led to our embassy being besieged and undermined our relationship with the Iraqi government and people. Serving the interests of Saudi Arabia and (extremists) like AQ (Al-Qaeda), Trump is taking us deeper and deeper into mid-east quagmire," Gabbard added.
She then tweeted about her own prospective policies as she continues her candidacy for the Democratic nomination for president.
"As president, I will end our servitude to Saudi/AQ and will provide the experience & sober, thoughtful, strategic leadership to the job of commander-in-chief that our country so badly needs."
Gabbard, who recently came under fire after voting "present" during Trump's House impeachment trial, has long criticized the Trump administration's foreign policy choices.
On Sunday, US forces conducted drone strikes on a number of Kata'ib Hezbollah bases in Iraq's western Anbar province, killing at least 25 individuals and leaving another 51 injured, according to the PMU.
Following the strikes, the Pentagon issued a statement saying that it had targeted three locations of the Iraqi fighters in Iraq and two in Syria in response to alleged attacks targeting American forces.
Kata’ib Hezbollah is part of the PMU. The PMU, also known as Hashd al-Sha’abi, played a key role in defeating the Daesh terrorist group that had occupied parts of Iraq since 2014.
