The US has reiterated that it encourages a “transparent” legal process in a corruption case against Delhi Chief Minister Arvind Kejriwal.
State Department spokesperson Mathew Miller said on Wednesday that the US was closely following actions taken against opposition parties in India.
Mr Miller’s remarks came hours after India summoned a US diplomat over a similar comment he made on Tuesday.
Mr Kejriwal, who was arrested last week, has denied any wrongdoing.
Hours before his arrest, India’s main opposition Congress party had held a press conference saying that its bank accounts were frozen by the tax department ahead of the general elections.
Mr Kejriwal’s Aam Aadmi Party (AAP) and the Congress have accused the ruling Bharatiya Janata Party (BJP) government of political vendetta.
The BJP denies the allegation, saying investigative agencies were doing their work independently.
On Wednesday, Mr Miller told reporters that US was also aware of the Congress party’s allegations that the freezing of their bank accounts “would make it challenging to effectively campaign in the upcoming elections”.
“We encourage fair, transparent, timely legal processes [in both cases]. We don’t think anyone should object to that,” he added.
