Washington, Jun 12 (IANS): US President Donald Trump has reportedly given White House chief of staff Reince Priebus a deadline of July 4 for a shakeup of the White House staff, the media reported.

Trump is considering bringing in former campaign manager Corey Lewandowski and deputy campaign manager David Bossie as senior adviser and deputy chief of staff, respectively, Politico quoted multiple sources as saying on Sunday night.

However, White House press secretary Sean Spicer denied the deadline in a statement to Politico.

"Whoever is saying that is either a liar or out of the loop," Spicer said.

Rumours of a staff shakeup have been a persistent theme in the Trump White House, but have picked up in recent weeks.

Communications director Mike Dubke resigned at the end of May and speculation about Lewandowski's and Bossie's futures has been rampant.

Spicer denied that Dubke's resignation signaled a coming shakeup, saying Trump was "very pleased" with his staff.
