"I am a farmer's son and I was here to raise the voices of farmers and jawans," Tej Bahadur Yadav said.
About 17 per cent of the over 6,000 'friends' in Yadav's accounts are from Pakistan.
Yadav was dismissed in 2017 after he posted a video online complaining about the food served to the troops.
Sharmila had claimed that the family has been unable to contact her husband for last three days.
She has sought a high-level inquiry into his disappearance as well as the recent rejection of his plea for voluntary retirement.
Yadav, who hails from Mahendergarh district, joined the JJP in New Delhi in the presence of its leader Chautala.
Yadav's family had expressed desire to meet the DG following which the meeting was arranged.
A bench comprising Chief Justice S A Bobde and justices A S Bopanna and V Ramasubramanian, that had reserved its verdict in the case on November 18, upheld the Allahabad high court judgment dismissing Bahadur's election petition against the poll panel's decision to reject his nomination papers.
He said he was shocked to know about his dismissal after being earlier asked to prepare pension and retirement documents.
It also directed the BSF to produce before it the investigation report and the steps it has taken with regard to allegations levelled by Yadav.
Yadav has now been shifted from the Line of Control to a nearby battalion in Poonch.
The move by the BSF has not been seen kindly by Yadav's family which alleged that the trooper was being "threatened and tortured mentally".
Tej Bahadur Yadav had posted four videos on social media in January, 2017, that showed him complaining about the unpalatable food at his camp along the Indo-Pakistan border in Jammu and Kashmir.
The home ministry conveyed to the PMO that there was no shortage of rations at any post in paramilitary forces and quality check is being conducted regularly.
Yadav had moved the top court challenging the decision of Returning Officer to reject his nomination papers from Varanasi Lok Sabha seat, saying it was intended to "give walkover" to PM Modi.
A staff court of inquiry found that Tej Bahadur Yadav guilty of making false charges.
The BSF took cognisance of the video and tweeted that an inquiry has been ordered.
The PMO has sought a report from the Union home ministry on the complaint by BSF jawan Tej Pratap Yadav.
Yadav said he wanted to contest the polls to eliminate corruption in the forces.
The claim comes close on the heels of a BSF jawan's video who alleged poor quality food was being served to the personnel in 29 Battalion in Poonch.
The Comptroller and Auditor General in 2012-13 had made certain observation in a report and 'we are improving it', he said.
Is social media the right platform to voice complaints about your employer?
The body of 33-year-old soldier from Kerala was recovered near his camp in Deolali Cantonment, Maharashtra.
The Border Security Force has transferred the Commanding Officer and the deputy of a battalion whose jawan Tej Bahadur Yadav recently alleged that poor quality food was being given to troops posted along the border.
'We owe our existence to the men in uniform, and we owe it to them to cleanse the armed forces by driving away every bit of corruption that eats into it,' argues Sudhir Bisht.
Jeet Singh, the constable, talks about how his colleagues in the force work in the absence of medical facilities or pensions.
"Anyone can go any day and anytime to any border outpost of the BSF and ask for food"
If he is mentally-ill, then why was he sent to the border and was put on duty? asks jawan's kin.
Whether his nomination was rightly or wrongly rejected by the Election Commission depends on his eligibility, the court said.
Alleging misconduct by its permanent workers, labour unions and contract staff, the plant management informed all stakeholders, through a notice, that starting Monday "normal operations" at the plant are being suspended.
