Blaha, who previously oversaw human-rights compliance by foreign militaries receiving American military aid, stated that Israel received "special treatment" from US officials regarding scrutiny of Israeli military abuses against Palestinian civilians.
This allegation was made as the Biden administration faces pressure over Israel's treatment of Palestinian civilians during the war against Hamas in Gaza.
Blaha held this position until August and was a director of a State Department security and human rights office.
Former US State Department official Blaha stated that his departure from the department was unrelated to the US-Israeli security relationship.
He claimed that Israel receives special treatment and undue deference from the US when it comes to enforcing laws regarding foreign militaries receiving American aid.
Blaha, along with other former officials, released a report highlighting civilian deaths in specific airstrikes in Gaza.
Two State Department officials, Andrew Blaha and Josh Paul, accused Israeli forces of acting illegally based on "compelling and credible" evidence.
Blaha's comments followed Paul's resignation in protest of the US providing arms to Israel during its war in Gaza.
A State Department spokesman, Vedant Patel, denied any double standard or special treatment towards Israel.
Israeli officials did not respond to a request for comment.
Israel has historically been the largest recipient of US military aid, with an additional $26 billion approved by Biden this week.
The text discusses the pressure on President Biden over his support for Israel during the ongoing conflict between Israel and Hamas.
The conflict began on October 7, 2021, when militant groups Hamas and Islamic Jihad carried out an attack on Israel, resulting in over 1,200 deaths.
Israel's response included an offensive in Gaza, causing widespread devastation and over 34,000 deaths according to local health officials.
The Biden administration is conducting reviews into allegations of human rights abuses by specific Israeli military units and will announce findings and potential aid restrictions by coming days.
Additionally, the administration is expected to disclose by May 8 whether Israel is complying with assurances that US military aid is not being used in violation of international or human rights law.
The Biden administration issued a new presidential national security memo in February, mandating Israel's written assurance and US verification that it is complying with laws regarding treatment of Palestinian civilians before military aid is provided.
Democratic Party members had pushed for this condition.
A report released on Wednesday by panel members urges the US to investigate specific attacks in Gaza, alleging that there is no evidence justifying the high civilian death tolls in 17 instances involving apartments, refugee camps, private homes, journalists, and aid workers.
If the US determines that Israel was wrong in confirming compliance with the laws, military aid could be suspended.
On October 31, an Israeli airstrike hit a Gaza apartment building, resulting in the deaths of 106 civilians, among whom were 54 children.
The Israeli authorities did not provide a justification for the attack, and Human Rights Watch failed to find evidence of a military target at the site.
Israel has stated that they are investigating several instances of civilian casualties.
