But Kushner's troubles were compounded at least in part because his initial security clearance application didn't list dozens of foreign contacts that he later included in updated submissions to the Federal Bureau of Investigation.
Jared Kushner, the president's son-in-law and senior White House adviser, was granted a permanent top-secret security clearance on Wednesday following months of uncertainty after he was stripped of his interim clearance in February, multiple news outlets reported.
In his statement, Mr Lowell added that Mr Trump's son-in-law had also sat for a second time with special counsel Robert Mueller, who is investigating the USA leader's campaign links with Russian Federation over alleged election meddling.
Kushner's access was downgraded in February when White House Chief of Staff John Kelly ordered that officials with interim clearances be cut off if they hadn't received permanent clearances.
"If I were Jared Kushner, I'd be sighing a breath of relief today", Mr. Zaid said.
Abbe Lowell, who has represented Kushner in the Russian Federation investigation, told CNN that questions asked of Kushner during the April interview were "the appropriate topics that Bob Mueller and his team were looking at".
Kushner was with Trump in New Jersey the weekend before Comey was sacked, and he was among the attendees at a June 2016 meeting at Trump Tower with a Russian lawyer at which the president's oldest son was told he would negative information about Hillary Clinton.
Speaking with CNN's Wolf Blitzer on Wednesday, Lowell refused to repeat the exact questions Kushner was asked by the special counsel, but he did share the topics they discussed.
"With respect to the news about his clearances, as we stated before, his application was properly submitted, reviewed by numerous career officials and underwent the normal process", Kushner's attorney Abbe Lowell said in a statement. Kushner previously spoke with investigators in November and was primarily asked about matters involving former national security adviser Michael Flynn.
Lowell disputed that the initial security clearance application played any role in the delay in Kushner receiving his final clearance.
It is not clear when Kushner's second interview with Mueller's investigators took place.
Giuliani also urged the swift wrapping of the probe in the backdrop of former FBI Director James Comey revelation in the last days of the 2016 presidential race that he was reopening the investigation into Hillary Clinton's email server, according to several media reports.
