BJP's prime ministerial candidate Narendra Modi too declined to meet the US team. He tweeted: "Refused to meet the visiting USA delegation in solidarity with our nation, protesting ill-treatment meted to our lady diplomat in USA."
Khobragade, one of India's senior diplomats in New York, was charged last week with visa fraud and making false statements.
She was accused by Manhattan's Indian American US Attorney Preet Bharara of visa fraud and exploiting her babysitter and housekeeper. She was handcuffed in public by law enforcement authorities in New York Thursday while she was dropping her daughter at school.
India has termed the treatment meted out to the envoy as "absolutely unacceptable". US Ambassador Nancy Powell was summoned to South Block by Foreign Secretary Sujatha Singh on Dec 13 and a strong protest was lodged over the treatment.
The US delegation is led by Congressmen George Holding (Republican-North Carolina), and comprises Pete Olson (Republican-Texas), David Schweikert (Republican-Arizona), Robert Woodall (Republican-Arizona) and Madeleine Bordallo (Democrat-Guam).
