Quoting "PMO sources", Kejriwal tweeted that the raids may be conducted on Deputy Chief Minister Manish Sisodia — known to be the Aam Aadmi Party leader's most trusted confidant — or Health Minister Satyendra Jain.

In another tweet but in Hindi, Kejriwal added: "Modiji, do what you want. Truth is on our side. God is with us. You can't do any damage to us."
मोदी जी आप कुछ भी कर लो, सचाई हमारे साथ है, भगवान हमारे साथ है। आप हमारा कुछ नहीं बिगाड़ सकते। (2/2)

Later, during a press conference on the odd-even traffic curbs, Kejriwal said the Modi government was "trying its level best to fail us".
"But they won't succeed because our strengths are truth and honesty."
The Central Bureau of Investigation (CBI) raided the Delhi Secretariat on 15 December, 2015, accusing the chief minister's principal secretary Rajendra Kumar of corruption. Kejriwal said the CBI searched his office too, but the CBI denied this.
Following the raid, Kejriwal had unleashed a vitriolic attack on Prime Minister Narendra Modi, calling him a "coward and psychopath" while intensifying the face-off between ruling AAP and Centre.
He had even dragged Arun Jaitley into the issue alleging that the CBI was primarily looking for a file which mentioned wrongdoings by the finance minister when he was heading the DDCA from 1999 to 2013.
On 22 December, Kejriwal had also called for Modi's resignation over what he termed was a "flop raid". During a discussion in the state Assembly on the situation arising out of the Delhi Secretariat raid and the DDCA row, Kejriwal called the day of the raid a "black day" and dared Modi to act against Madhya Pradesh Chief Minister Shivraj Singh Chouhan, his Rajasthan counterpart Vasundhara Raje and External Affairs Minister Sushma Swaraj.
"I seek the Prime Minister's resignation for conducting such a flop raid and for misusing the CBI. If he uses the CBI to get any file then the country will have no democracy left. Tomorrow there can be raids on any Chief Minister. This is dangerous for the country's federal structure," Kejriwal said.
The chief minister, against whom Jaitley has filed both civil and criminal defamation suits, further alleged that the CBI was specifically looking for a file "containing a note" with "incriminating" details.
"A DDCA whistle blower used to meet me. That officer told me that there was a meeting of DDCA officials, where Jaitley had told them no not worry about SFIO as he will get it compounded.
"He (Jaitley) said that he will ensure quashing of cases that come to Delhi police and, if AAP sets up a commission of inquiry, he will get it null and void through 'our special man' LG. It was written in that file," Kejriwal claimed.
Kejriwal also defended Rajendra Kumar against allegations of graft committed in his official capacity under the erstwhile Sheila Dikshit government, saying the raid amounted to mental harassment.
