Whitaker’s origins are obscure, but after leaving Cambridge he first attracted notice as a poet, attending the famous literary club that met monthly at the Mermaid, and publishing verses in several languages as a preface to his friend Thomas Coryate’s Crudites in 1611.
Whitaker’s mother may have come from Peterborough, and it is possible that his first wife’s family, who owned land in nearby Farthinghoe, recommended him to the 2nd earl of Exeter (William Cecil†), who held the liberty of Peterborough and presumably nominated him to Parliament for the borough in 1624. Elected to the junior seat, he is often difficult to distinguish from William Whitaker, a lawyer who sat for Shaftesbury.
On 7 May, when the committee for grievances’ report on religion was delivered, Whitaker added to the charges against the Arminian Bishop Harsnett of Norwich, who had been accused of mulcting his clergy and discouraging preaching.
Some time during this year Whitaker bought himself a house at Turnham Green, near the house of his former employer, Somerset, for whom he continued to act as agent.
Whitaker was returned for Peterborough for the third time in 1626. He was immediately appointed to consider two measures revived from the previous Parliament, one for the earl of Dorset’s estates (13 Feb. 1626), and the other a bill committed upon his own motion against scandalous and unworthy ministers (15 February).
As a servant of the Privy Council, Whitaker’s main task in this Parliament was to protect the duke of Buckingham from attack and obtain supply. He moved on 1 Mar. that Buckingham’s counsel be permitted to speak in his defence.
In September 1626 Whitaker was among those appointed to collect the Forced Loan in Middlesex.
Whitaker was named to committees for bills for Church unity (7 Apr.), against scandalous ministers (19 Apr.), and for the better maintenance of preachers (7 May).
On 5 June, during the angry debate on the king’s message forbidding attacks on the state, government and Church, Whitaker moved that the proposition of John Selden*, naming Buckingham as the cause of all the state’s troubles, might be deleted because it was not proved, and expressed the rather forlorn hope that ‘the moderate proceeding of this committee may yet make this a happy Parliament’.
In the second session of the Parliament, Whitaker was named to committees to facilitate more widespread preaching (23 Jan. 1629), to prevent the begging of forfeitures before attainder (23 Jan.), to prevent the sale of judicial offices (23 Jan.), and to clarify the laws against recusancy (28 January).
The Papists in three parishes came to 800. We have a colony of Papists, who are a grievance to the inhabitants in their birth, in their life, and after their death ... We, the ministers of justice, have done our best to cast out these dwellers, but they are too strong for us; I hope our justices will take order. Palmer, Cole, St. Johns, priests and prisoners in the new prison: these go about all day to pervert people.

Immediately after the dissolution Whitaker was sent to the house of (Sir) John Eliot* to seize his papers.
